That one puzzle game they had on Facebook that was like a combination of Collapse and Bejeweled
The Beatles Rock Band had such a unique awesome look to it, that just transported you back to the 60's and its beautiful! Reminds me that I should play it again, give it another go, since its been awhile. Love their songs, and they are one of my favorite bands.
U2 / ELP / Bruce S. / CSN / ELO / BTO / ZZ TOP / The Fray / Ted Nugent / Bob Seger & TSBB /The Eagles / Steppenwolf
Green Day Rock Band wins because of the simple fact that if it wasn't for Wii + GH3 guitar bundle being cheaper than Wii on its own, I would have gotten into music games via GDRB.
Wishlist (possible artists):
 The Killers
 The Cure
 Sum 41
 Linkin Park
 Green Day
 The Offspring
Lego followed very very closely by Beatles and Blitz.
I popped in Lego the other day and was still amazed at the stages and art direction. Not to mention it's the only export I have where I haven't one lightered and hid a single song.
Still wish RB3 had as much customization. I want my snazzy RB3 Rock Den with monkeys and inflatable pigs.
Liked Blitz ok, but Beatles is the peak of everything. It's really the best thing Harmonix has done since Rock Band debuted. I'm not even a huge Beatles fan but the execution of that game was outstanding, everything from the look and style to DLC.
Does this signature annoy you?
Imagine if Paramore had their own game, oh where oh where is Cipher?
The Cure 
My Chem. 
Green Day Rock Band
I am not saying it's a better game than The Beatles, but its a better Rock Band Game. They are both great, but Green Day wins because of the fact that the songs are just better suited to the game, that and my own personal love for the band and the music makes the choice easy for me.

Although I prefer to play the music of Green Day in Rock Band, I'd have to give a tie to TB:RB and Lego for the games themselves. I think, as far as games go, Lego might just inch out the Beatles.
But I believe in this and it's been tested by research: he who  nuns will later join the church.
