Well considering all the Unibodies have the exact same keyboard, there are only two choices in your "poll".

As for me, the macbook "chicklet" keyboard is probably one of the best i have ever typed on. took a bit to get used to coming from PC and gaming keyboards, but once i got used to it, done deal.
 
Zero difference.

They top, flat key surface is virtually the same size, just without the beveled edges on the Unibody vs the old G3/G4 iBooks
 
I don't know a whole lot about the new MacBooks, but I can tell you from experience that the G3 iBook keyboards sucked like nothing else.
