If the super skimmer works, you may as well keep it for now – if other skimmers are better, it's only marginally...mostly they are just more popular – and prioritize the other things you need. (The skimmer can always be replaced later if it really has problems.)
If/when you do replace it, I'd check out Tunze and AquaC for replacements.
Tunze's
DOC Skimmer 9410 ($330) would be my preference on their side. Top-flight needle-wheel skimmer with some of the best features around. Very easy to clean.
AuqaC's
EV120 ($300) would be my preference on their side. Old-school skimmer – easy to clean and awesome in that it takes ordinary hobby pumps to run.
I have both of these skimmers and really love both of them.
