I have both. I also love the grashopper gtx. Tough call overall, they are very very similar. Very similar feel overall imo, but the GTR is noticeably wider (while maintaining almost the same feel in play). If wider is your thing, you will prefer the GTR over the GTX. I do like both, the gtx is a great through, so is the gtr. It’s kind of like the difference between a shutter and shutter wide angle. Hopefully this helps somewhat.
