I've also worked with CSV (barely) and SVN (more extensively) and I was blown away by Git.

You can have real branches! Many of them! You don't have to manually merge them! It's decentralized, you can have multiple origins, it lets you work offline! The list goes on and on.

There were many compelling reasons to switch to Git. But for all the articles about jj out there, I've never read any compelling reason to switch to jj. "It easier", "the commands are somewhat more ergonomic"... that's all?

One thing JJ has that git doesn't is the concept of first class conflicts. In JJ, rebasing or merging never fails, but it might record a conflict to resolve later. Git, on the otherhand, forces you to drop we everything to resolve conflicts immediately. It sounds like a small thing - but in my experience, being able to resolve conflicts later when I feel like it is absolutely amazing and really helps reduce context switching.

You don't need to switch from git to jj. You just try out jj on your git project and see if it clicks. If you don't like it, you just don't continue using it.

Ergonomics are everything. Its why there are zillion IDEs, terminal apps, keyboards, mice, etc.

Hot take, but I personally hate git and almost always rely on a GUI tool or IDE integration to interact with it.
