It's a double edged sword.
s4 has lower compression, so it's a little less hostile to extreme amounts of boost
s5 has higher compression, but if tuning is proper and the fuel/timing issues are undercontrol, it would make more power.
FWIW the s5 is a little stronger motor than the s4's as far as handling super high hp applications.

news flash:
boost is relative. SO before you go on and try to hurt your head on this one. Go look up, how compression works with boost, and you would understand that the argument is pointless. Far too vague.
