ASM skimmers are classic and work well. If it's not broke why fix it because of some Arbitrary Manufacturer's rating? But between those two you listed I'd go with the Reef Octopus Elite. For a needlewheel skimmer though I'd check out the Aquamaxx line or the new IceCap line with a stock sicce pump instead of a modified one. Those are good price alternative. If price isn't an option I'd look at the MRC or Royal Exclusive line.
For larger tanks I tend to lean toward workhorse skimmers like Becketts or Mazzei Venturi based. Life Reef and MTC make great venturi based skimmers. MRC and MTC make great Beckett skimmers. Another alternative that works better on larger tanks vs smaller ones are the AquaC EV line. With these types of skimmers get the tallest body you can fit. I know Life Reef and MTC will customize a skimmer to fit your requirements.
