You buy what you like, everyone else buys what they like. What does it REALLY matter WHAT brand you fly as long as you fly? I own an original Align 450 pro, I have two KEEP R/C 450 pro's and have been flying EXI 450 pro's till they dried up. Yep, the align has NICE quality, the EXI-450 pro is BETTER than the KEEP R/C 450 pro, just a little less quality than the Align. Bottom line is I fly them all and it doesn't really matter if they are set up correctly, and some of the bad quality parts on the clones are replaced with Align parts when they need replaced. I think that covers it.
