octopus xtreme 160 vs SWC cone 160

[Spiny]

I'm looking for a new affordable skimmer. I'm running a 66g SPS reef. I'm hesitating between those two; the octopus extreme 160 and the SWC extreme 160 cone.

I will be upgrading to a 180g sooner or later. So I'm going for a skimmer I'll just be able to buy another one of the same and skim my tank. So the main question is: will 2 of either of those be able to skim a 180g medium stocked SPS tank.

Also, are those comparable? The octopus looks very well built, but the pump of the SWC sounds better. Any input will help
