alt Hacker NewsP4 is also really well integrated into IDEs and UE Editor so that I don't need to think about it as much as I need, compared to Git. Locking assets, releasing them, merging into streams etc., is overall pretty streamlined. When it works, it's great, but when it doesn't work though, it's pretty hard to diagnose issues.
One of the many points of git's design is that most of the steps you need to do in P4 are not necessary at all. You do not "lock assets", you do not "release them", there is no "merging into streams" equivalent.
The entire workflow with git avoids huge amounts of the cognitive load of using P4, which in turn means that integration with IDEs becomes much less important.
I worked with P4 around the time I first started learn git (coming to both from SVN). P4 struck me as "what a for-profit corporation would imagine a VCS should be like, if they'd never seen git". So glad to be far, far from that particular tool now.
