48 gallon cube skimmer recommendations

[TangingOut]

Hi, I'm getting back into the hobby after 5 years and bought a used skimmer which looks to be undersized. So now I'm looking for recommendations for my 48gal cube with a sump. Let's say 55gal system that's going to be med-heavy stocked. Currently comparing Nyos 120 and Bubble Magus curve 5

Hob, sump?

My 40 gallon with a 20 gallon sump has a curve 5 , very happy with it.

In cabinet sump. It's an Aqua forest Ocean guard 275. Protein skimmer chamber is roughly 8x9.5"
