They work as well as perforce.

I disagree. Perforce requires you to be connected to the depot (ignoring reconcile offline work because that’s a break glass feature), and allows you to check in when you are not synced to latest. It forces you to deal with file level conflicts at time of update, not at the time of submission, and the intermediate state of “I have local changes that the remote/server doesn’t know about” is considered exceptional rather than the norm.

I can count on one hand the number of times I’ve had to reconcile offline work in the last 18 months, which is the equivalent of every merge commit in git.

P4 has file locking and automatic file type locking on checkout to prevent conflicts. It honestly goes a LONG way and the games industry is built around that tooling.
