LifeReef are awesome skimmers. The best venturi on the market, IMO. Only downside is a bit more power on the pump. I would use one if you can fit it in the stand... the one that I have is 48" tall, so I can use it a basement sump only.
Beckett and DownDraft will outperform all needlewheels that I have ever used... even a BK or Deltec. Again, need more power hungry pumps, but are performance monsters. I just replaced a needlewheel running 32 watts with a ETTS with Mag 12 and the Mag 12 is using 72 watts at the current spin rate... so 40 more watts. This is worth it to me to pull more gunk out of the water.
For needlewheels, just look for a proven combo. I have a RO with a sicce pump that is really good, but the same skimmer with the RO and Bubble Blaster pumps leaves a lot to be desired and I cannot recommend them. I have tried a few of the cone simmers with bubble plates like Magnus and AquaMaxx, but they are kinda just OK like the recent RO line. Proven combos like ASM and EuroReef are as good as any new skimmer today outside of Bubble King, but they are not sexy choices.
