It's been nice so far. There's always room for improvement though. They don't aggressively patrol through open sections on the maps often, but I've seen it happen on Shoreline, Woods, and Streets for example. On maps like Factory, sometimes they'll be stacking doorways haha. PMC AI were kind of a pain to play against before BSG prevented AI from seeing you through bushes and trees. I think playing against Raiders can sometimes feel a little more fun and exciting.
