I haven't seen it play on the PS3 but I have seen it on the 360 briefly (30-40minutes). Load times were definitely slow but weren't too ridiculous. I think it was just the sort of thing that starts to get annoying while you are trying to play through sections of the game.
I've played the PC version and there are some times when you are trying to complete quests that you are loading new areas a whole lot so it could become annoying. But the reason I am posting this is to say that the PC version even had some slower load times so I think overall its just a shortcoming of the game that you have to deal with...it will just be an issue of how long you wait. If the achievements are something you enjoy I would say go with that. If you don't mind giving up the achievements for a bit of reduced frustration on load times then go with the PS3 version. I'm pretty sure thats what your choice boils down to, but again I haven't played the console versions extensively so I'm going off of limited knowledge.
