2 Bak Paks or Remora... Which is better?

[RegalFlush17]

Here is the situation. I have a 20 gallon reef with softies and LPS accompanied by a Bicolor Blenny and Percula Clownfish which has running on it a Hang-On Remora. I am starting a 37 gallon Reef with 20 gallon sump with SPS and clams and will also be modestly stocked. I have a spare Bak Pak and in Sump Bak Pak that would both be used in my sump, and I was wondering if I should use the remora hang-on in my sump, use the 2 bak paks, or get a new skimmer such as REmora pro in sump and sell the 2 bak paks. Any advice would be great.
