I think there's fun to be had with either the GH:WT bundle or the RB2 bundle, provided you get perfectly working instruments. Most casual music-gamers who want to play along with some fun songs on occasion (maybe with the wife, relatives or on weekends with guests) will have a good time with the hardware and game from each.
Guitar Hero and Rock Band take different approaches at the same thing:-single-player/multi-player:
Guitar Hero takes a more cartooney, video-gamey "fun" approach and has a good single-player career. Rock Band (esp. 2) emphasizes the multiplayer band element, and is on the serious side. In RB2 I'm mostly just doing "quick-play" of songs I like to play for fun and don't feel there's enough end-of-song info, nor trying to get the best score/"stars" for each song... but Guitar Hero does this much better.-Guitar:
I think the guitar charts in both games are very good and prefer the fun nature in GH over the more "realistic" of RB. Many disagree, so YMMV. Hardware: While the RB2 strat has more comfortable frets, I like the GH:WT tap/slider (fun!) and clicky strummer.-Drums:
Rock Band (1 or 2) is the hands-down choice
, and I doubt anyone would argue this. In Rock Band, overdrive is a crash at the end of selected fills when the meter is full, and this feels natural. In Guitar Hero star power is hitting yellow+blue anytime the meter is full, which feels wrong. Hardware: Rock Band 2
, but I have a lot invested in a RB drumkit so I've never really seriously tried the GH:WT drums. Plus, playing 5 lanes is the proper way to play drums, and RB drums in Guitar Hero are gimped to 4 lanes... ugg!-Vocals:
dunno, I don't sing.
I'm assuming both games are pretty much the same experience..? -Setlist:
Based on just the songs on the disc, I like more
songs in GH:WT over Rock Band 2. With that said, the best songs in RB2 are better
, but the worst songs are a lot worse. Guitar Hero seems to focus more on radio-friendly familier music, and Rock Band 2 has a little wider range, with some odd alternative and hard-core metal. DLC: Rock Band absolutely
. For Guitar Hero, having World Tour+Metallica+Smash Hits discs yield an incredibly awesome setlist, but the dreaded disc swap is needed. Rock Band has many of those songs, plus hundreds more -- with greater variety... and are available separately and playable via the RB2 disc. "RB DLC FTW" -Upcoming:
Rock Band: The Beatles looks awesome (albeit stand-alone from the platform), Guitar Hero 5 is an unknown.
