Contentful

Contentful is well suited for folks who want a simple, clean, easy-to-use interface for a JAVASCRIPT website. If you do not want a javascript website you should look [elsewhere].
Jennifer Garcia | TrustRadius Reviewer

Google Tag Manager

Google Tag Manager is well suited when the marketer or marketing team does not work closely with the developers. In this scenario, it means that the marketer can deploy 3rd party tools such as live chat widgets, advertising pixels, and much more themselves in a timely manner. Google Tag Manager may be less relevant in an organization where the marketer is also the developer or has a strong development background, where they can implement the 3rd party tags directly on the site when they need. But even in this instance, there's still great benefit in using Google Tag Manager.
Quentin Aisbett | TrustRadius Reviewer

Pros

Contentful

  • Clean, modern interface (not clunky and outdated, like WordPress)
  • High degree of flexibility (I can structure data any way my clients need)
  • Enables headless frontend (i.e. I can build any frontend I want without having to change my CMS)
Andrew Folts | TrustRadius Reviewer

Google Tag Manager

  • Selecting elements on a site [object, class, cookie, etc] (to later fire an event, send some data, etc) is very easy with triggers. Want to add an event when someone clicks on a button? Super easy. It was many many DOM selectors and you can even add custom functions if you need to do something more specific
  • In general, firing events in different circumstances is very easy mixing triggers and tags. You can track almost any element of the DOM and do whatever you want with it.
  • Testing is a great functionality. Only you can see what's on the site and you can debug it easily by seeing which events or tags were triggered and all the DOM elements involved (and why they matched the trigger).
  • Working in environments (staging, production) and versioning is easy to do, deploying changes in 2 clicks.
Santiago Valdés | TrustRadius Reviewer

Cons

Contentful

  • The new Contentful "branches" feature looked promising (it appears to mirror a git-like repository) but it requires the CLI, which isn't necessarily practical for teams that aren't current CLI users. It would be nice if the management of this feature were available via the UI (without that it causes more confusion than anything).
  • The Contentful data modeling method makes for a bit of an awkward SDK developer experience in some strongly typed languages like Java. Most things that you might need can be accomplished, but it feels like the experience could be smoother.
  • It would be nice if there were a way to migrate data between spaces (e.g. from your staging space to production).
Eric Mason | TrustRadius Reviewer

Google Tag Manager

  • There are several good integrations, but there can always be more. Native tracking for call tracking solutions, analytics providers, non-Google advertisers would be top of my list.
  • Documentation is just dreadful. Luckily there are some awesome folks out there doing crowdsourced tutorials (shout out to Simo Ahava) but by and large the Google Tag Manager instructions are worth what you pay for them.

Google Tag Manager makes tracking traffic to our websites effortless, which enables our developers to focus on other tasks. Setting up a new instance takes only minutes and additional scripts can be added/modified without touching the source code of a site in production. This enables our marketing directors to coordinate tests and experiments with minimal effort.

Google Tag Manager is the definition of a learning curve. At the beginning, you can barely do the minimum and it can seem questionable as to why you would use it. However, as users begin to learn its offerings and see how it can do much more, they will have a moment where GTM becomes a tool that empowers their ability to track and efficiently collect data for important business questions.

It depends wether you are seeking official support from Google itself, in which case it would be rated very low because it's not their business model, they would rather have you work with one of their Google Analytics Certified Partner (GACP).In terms of self-served support, Google offer extensive documentation at https://developers.google.com/tag-manager/, recently revamped training (https://analyticsacademy.withgoogle.com/course05/preview), has active forums and user community (https://plus.google.com/u/0/communities/104865292981489764063) which can typically answer even the most advanced questions.

I thought there was a little bit too much emphasis on AdWords stuff, not enough on the generic application of GTM.

Planning and communication will help greatly with an in-house implementation. If there are large teams, try to limit the number of people involved to 1-2 developers (back-end dev may be necessary depending on your platform), one analytics marketer and one project manager.

Alternatives Considered

Contentful

Contentful offers a great deal of features for a relatively low price. This is what ended up persuading us to purchase it. We also gathered that this was one of the more well-rated products out there, which was encouraging. It definitely stacks up well against its competitors.
Nathan Richardson | TrustRadius Reviewer

Google Tag Manager

We moved to GTM from a standard Google Analytics implementation. GTM is much more flexible and easier to make changes, especially as the changes relate to multiple sites and environments. While there is a learning curve when figuring out how to use GTM, I believe the change has been worth it because it helps us understand at a more fundamental level how our tracking works and gives us a lot more control over what we track and how.
Ben Rubenstein | TrustRadius Reviewer

Return on Investment

Contentful

  • Positive: faster changes and new associates can easily navigate without prior training/knowledge of CMS to make content updates
  • Negative: Our website manager/provider can keep certain abilities (like changing specific images) so they can charge a fee for making the change
Nathaly Sierra | TrustRadius Reviewer

Google Tag Manager

  • GTM is very useful to determine if a particular element on the site is useful (i.e. is it being watched, is it being clicked, does it help customers navigate through more pages). As an SEO person, I can use this information to decide what to optimize for but also to track progress and see improvements in engagement.
  • With the use of Google Tag Manager, I was able to easily inject an A/B testing tool which lead to several improvements in lead generation.
