Better all around....no, sorry its not....but if it is what you want then go for it, its your motor, build it however you like.
Just some thoughts and all are arguable....
more ecomomical to build?
quicker revving and accelerating with stock heads?
better mileage ?
more stabil pistons?
less piston speed for the same rpm?
much less long term wear?
better bore to stroke ratio?
much better balanced package for the street in a light car where big torque is not necessary?
