Pros

Google tag manager is easy to work and use. There are resources and top-level support from the platform itself.
GTM allows me to inject code onto my site including snippets without having to ask my DevOp team to do it for me.
It's pretty simple. This allows us to add tags and track certain data points and key metrics on our site and see how effective we are at retaining and keeping users.
Witth some research, the possibilities are endless when it comes to finding out information about visitor behavior. Very useful for optimizing user experience.
Google Tag Manager provides a one-stop place to manage all analytics containers (also called tags), like Facebook Pixel, LinkedIn Pixel, Google Analytics code etc.
The user interface is fairly intuitive but there is a big online community out there that usually have solutions to anything you may want to do with Tag Manager.

Cons

You need a little knowledge of what is about a tag and how it works. All definitions could be confusing at the beginning but with more time and experience it takes easier.
Google Tag Manager slows down a site's download speed. And that's the only thing I don't like.
It's not intuitive at all but requires, at times, quite a lot of work to figure out how to set up different tags.
Occasionally the data can be questionable and we have to go diagnose how the tag is set up. This is likely not a problem with non-custom websites however.
Sometimes the tag doesn't fire and it's hard to manage the cookies and tags when there are many people working in the same environment.
It was a bit hard when configuring the first time, but after that, no issues. Therefore nothing to dislike about the tool.
