Overall Satisfaction with Google Tag Manager

Google Tag Manager is used by all clients who have tools outside of the Adobe suite (Adobe has its own TMS which comes free with the Web Analytics platform). GTM is simple, easy to use, has enterprise level features (such as multitasking), has its own debugging panel and the best part is that GTM documentation is public and abundant which is untrue for any other TMS.
  • Ability to add custom tags which do not have templates.
  • Easy integration with other tools that are part of the Google Suite.
  • User friendly interface and help section.
  • To publish a tag, the entire container needs to be published or a new workspace needs to be created. Some TMSs have the functionality to activate a tag without having to publish an entire container version.
  • It does not support advanced inbuilt functions such as cookie storage. But, custom scripts can be written.
  • Efficiency has improved thus saving a lot of hours. Tags are quickly configured and the need of communicating with Dev teams is almost eradicated unless you want datalayers to be placed.
Simpler to use and comes free of cost. It has enterprise level features and gives strong competition to any other TMS. If a company has Google Analytics or any other Google Suite product, GTM will easily integrate with it. The only reason I can think of as to why you should use another TMS is if you are interested in other products of that respective suite such as a Tealium Audience Stream which is way more advanced than the Google Audience Builder.
Less appropriate if the organization has multiple websites/departments who want their own profile. In this case, if a tag has to be configured for more than one website, it will have to be configured equal number of times. A TMS like Tealium has the functionality to add script libraries where the tag will work for multiple properties even though configured just once.
