Personally, I think kingside is better because it doesn't leave a weak, unprotected pawn.
Another reason why i see red when they o-o-o. They have to spend a move defending it or allow it to be captured. I like the mental side of when they move the king to defend it. The king running in the corner.
.
O-O is often sounder, but less aggressive. O-O-O often leads to more exciting games, but both are fine if played correctly
Dude, that's really NOT true, it all depends on the position!
