I also have both markers at the current time, my clone gt does get a lot more use though. The g6r is one of the best poppits i have shot, it gets incredible efficiency on a 68/4500 fill. Here is a point form list of what i like about the g6r
-great feeling ergonomics
-2100+ shots per fill (claimed with hp poppit)
-lightweight and snappy marker
-reliable when the pressures are set properly
-great stock trigger
Now for the Clone gt
-best efficiency out of any spoolie out there (1700 shots per 68/4500 fill *claimed*)
-ergonomics are good (i had my frame rounded off to make it better then the g6r, but without that the sharp edges get a little annoying)
-soft shot, and very little kick
-bolt is removable through the back, no tools required. Very easy to service
-stock barrel is very good in my opinon
Overall i would chose the clone gt, it converted me to spool valved markers and i do not intend to look back.
