ER RS-80 vs. PM ES100 Venturi Skimmer

[bv_reefer]

ok so i'm converting to an sps frag tank and gonna plump the tank to a 20 gallon sump, and after some thinking i've decided to dish in and get a decent skimmer, i'm really hooked on the euro-reef RS-80, but now also saw on oceanaquatics.com a nice PM ES100 Venturi Skimmer >http://oceanaquatics.com/store/produ...nturi-Skimmer/

what would you guys go for, which ones better suited for a 33-gallon sps frag tank, it's barebottom i don't know if that really matters
thanks, lol i know i've been annoying with all the skimmer threads but wanna know the pros and cons of each, so i get one that'll last-
