The Q and N just coordinate better I think. They move around each other in the same space very nicely. Q and B require the same squares and lines and can get in each other's way.
why is Q+N considered better than Q+B????

Smothered mate is why Q+N is way cooler-looking than Q+B. Sometimes. When smothered mates actually occur, anyway.
I saw this one the other day when I should have been studying:

We were talking about this in another thread... Capablanca allegedly said Q+N were better than Q+B, Flear believes they're roughly equal, and Watson says it's complicated. So it's not so simple as, people consider Q+N better than Q+B. ;)

Capablanca did say that. It's in his book 'chess fundamentals' which is so old now I guess it must be out of copyright.

Having the same moves (Q+B) is sometimes better--as in Q-B batteries. Q-N seems better as they complement each other (as stated above by sstteevveenn).

People argue about Q+B having a general weakness on one color complex, while Q+N can freely threaten more along the board.
To be honest, I think that both have winning chances. Its just a matter of preference.

I'm not familiar with Q-B batteries. As far as I know (and as explained by Demitri Martin) there are no B batteries.

Tell me if I'm wrong in my chess terms... diagram has both Q-R-R and Q-B batteries on the queen side for white. What is that formation called?

It's called mate in 1.

Yes, it's a mate in 1, but I mean the formation of the white bishop and queen. I'm just verifying if indeed it's called a Q-B battery (similar to the more familiar Q-R battery).

Yes, any formation in which an attacking piece is defended by a piece which can move along the same diagonal, rank, or file is a battery. Most common are queen-bishop, queen-rook, and rook-rook.

Thanks--that should answer TheGrobe's post.
just wondering why ppl say Q+N is better combo than Q+B?????
