Will Guitar Hero 4 be better than Rock Band?

[L.C.E.C.]

You know, Whenever Rock Band 2 uses real-life guitar heroes/musical heroes/band heroes (real musical likenesses) like in Guitar Hero, then I will be the one saying OMG! OMG! LOOK! THEY COPIED!!! RIPOFF!!!, just like everyone is calling GH4 a ripp-off when it's not.
