which skimmer is better?

I have no experience with the Deltec, but the Remora are excellent skimmers. I actually used a standard Remora (rated 75 gal) for a FOWLR 90 gal. It worked great. The 90 had a blue lined snapper, miniatus grouper, pink tailed trigger, and picasso trigger. The tank was overstocked but the skimmer kept on producing thick black smelly stuff. The water parameters were good.
