Might be controversial, but I prefer this ever so slightly to Guitar Hero III - mainly because it just feels more dynamic. More dynamic in its setlist (without those rough covers which GHIII still had [like Paranoid + Holiday in Cambodia.. ooof]), its wide docket of pretty venues, campaign, and of course full band gameplay. Charts are still weaker than GH overall (very possibly due to Harmonix's attitude that rhythm games should be played with 'music >> gameplay' in mind) but they're still mostly fun - and holy hell is it ever a VAST improvement over almost everything wrong with the first Rock Band - I'm very impressed with how much this still holds up! Still a few dropped notes here and there (especially with long lines of strum salads) and I'm not sure if I'm a fan of how much repetition you can expect in the campaign setlists, but there is just hours upon hours of good content here (with DLC support!) even just as a solo guitarist. Still can't touch Guitar Hero World Tour at all though imo.
