Google Tag Manager

If you have a marketing department that wants to be agile and measure valuable goals for your company, then GTM is the way to go.You will be able to track almost any event of value that you want on the site (without adding any extra code, thanks to auto-event listener), add new marketing tools if needed in minutes and send events to multiple platforms. This has huge value for your company if you think about it: measuring your efforts quickly and changing course if it is not working can save tons of money. I believe almost anyone who has a site on the internet can benefit from it because of how much time it saves (considering it's even free!).Just beware: GTM opens the door so you can add any piece of code you want. Someone without much experience can overload the site or affect site speed

Pros

  • 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.

Cons

  • For someone who's just starting, it can be overwhelming to understand how it works. Onboarding is not easy and even thought it has improved a lot since it started, still has a way to go so you can actually understand what's going on.
  • Documentation is very poor and generally you are on your own if it doesn't work right. Try searching for GTM gurus like Simo Ahava or ask forums, but general use cases or more docs don't exist.
  • Debugging is a bit hard. Even thought you have the test functionality (which is useful) in some cases when you reload the page or the action takes you to another page (form submit, redirect, etc) it can be hard to debug.

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.

Usability

Google Tag Manager, like other Google products, is focused on user-friendliness. All buttons are clearly labeled, documentation is thorough and plenty of tutorials exist to help answer any questions. The layout and menus in Tag Manager are clearly labeled and consistent with other Google products.

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.

Implementation

Google Tag Manager9.8
Based on 2 answers
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.

Google Tag Manager is free, which is the most important aspect of our business. The other tools work well, however, have heavy fees associated with their use.
