is the console (specifically ps4) versions just as buggy as PC?

No. You don't really have to worry about soft locks while starting new save files, but the glitch with the soft lock during dot's dialogue at the start is still there IIRC. The load times ARE more inconsistent though.

Note: I am referring to the ps4 version. The other versions besides PC suck.

It's a bit more stable from what I've been able to tell. Also, as far as load times go, they are a tiny bit slower, but iirc, it's not a MAJOR difference, and really won't matter unless you're going for world record
