I downloaded and tried the demo on Xbox 360.
I greatly prefer the PC version. Blizzard did an admirable job porting the game to consoles, though. Solid 60 fps (might have to tweak my PC settings a little), and the controller doesn't suck hard when you're fighting. I haven't tried a ranged character yet, but the barb did alright.
To say it's (the controller) better is an interesting statement. Inventory management is absolutely a chore. I fully backed out on more than one occasion when I didn't want to, and it just takes longer in general. Extra button pushes to enter specific categories, and another button press to actually see affixes. Overall, it's a chore. I think they did the best they could with it as the PC method wouldn't have worked as well. Elements would be too small.
I haven't had a chance to try ranged combat, but my concern is how something like M6 would play. I wouldn't be able to try that out on the demo. Combat was still a bit clunky, though. A lot of missed swings, and let's all consider that the evade is there for a reason.
Skill management appears similar to PC. I'd have to put more time into the demo to really give it a try, though.
Auto-loot of lootables objects (bodies on the ground, mostly. Racks still require interaction) is nice, and again exists due to how imprecise the controller is. I also liked the quick compare that pops up when you pick an item up. Lets me know if I should bother going into my inventory or not right away. It's a thing that only matters on your way to 70, but for that it's nice.
I can see couch co-op being fun, but it wouldn't be better for me. So, not knocking it, it just wouldn't be a better fit for me over b.net.
As for reviews, they were comparing console versions with smart loot against vanilla and the AH. They are out of date. If one is too lazy to try the demos, they simply aren't allowed to complain if they realize they bought the wrong version.
