What is the best general SNG for someone trying to build their BR, Heads up, 9 or 18 player?

just out of curiousity, Just finished BARELY ITM on an 18 table but there was a few times where the lady snatched my ass out the fire...

also I play on stars, what seems to work out better for most people, the std SNG or the turbo?

I generally play a really solid tight game until blinds get high or I'm on the final table
