Ya, barb fittings on external pump didn't make much sense to me either.
I'm not sure on the noise, both have fans, so probably similar. They might be talking about the yellow pumps too, Blueline HD which are PanWorld Japan brand pumps, where the BL1100 is a china import or Tawain region, same as GENX. I would say if you need it pretty quickly, we can setup you up the BL1100, if you can wait for GENX, i will be having them on sale for 119.95 when they come in, so little cheaper on price, but not too much.
Some feedback on the SCWD, it switches pretty fast on a GENX, Jeremy has GENX running on his SPs tank with SCWD and it goes back and fourth pretty fast, little too fast, but he wanted that extra flow.
thanks
