Deltec skimmers are some of the best needle wheels. I never had one perform as well as a Becket, Downdraft or Venturi (LifeReef, anyway), though. Bubble King is better than Deltec, IMO. If you are looking BK or Deltec, see if parts are easier to get now... it used to be a real problem to get parts in the US and I was able to buy a Deltec for pennies since they guy could never get an impeller (I had to wait like 4 months on it)... they could be better now.
Any of these above will crush your standard RO, eShoppes, BM, etc. Bubble plates and cones are a marketing joke. There are a few exceptions to this where the manufacturer happened to just "get it right" ...like older Sedra Powered ASM and ER skimmers are better than most of these. The Sicce PSK powered RO line was really good, but they switched pumps and the newer models did not skim as well. I will never sell my Sicce PSK powered RO skimmers... they are REALLY good - I have told myself to buy any used ones that come up, but I never see them.
I do not usually suggest Beckett or Downdraft skimmers since they require some tuning and a power-hungry pump and are not for the faint of heart, but they really can perform a lot better... and they should for the extra work and cost. Usually large-tank people can still like these, but they are long past worrying about the difference in a 60 and 110w pump.
If you can fit it in the tank, get a LifeReef. I do not always use them in my tanks since the one that I have is 36" tall, but I always use them when I have a basement sump where height is no issue. They do make a 24" model, which I do not have, but I should probably buy one. I will never sell this skimmer.
