I have owned expensive SV sight trackers, STI Apeiro, plain Jane STI Edge, custom FLDC Gans gun, and now a Limcat Perfect Sight. Although I’ve noticed small differences in each I can honestly say that with time on each gun I could shoot them all equally well. To me it comes down to preference and the gun builder for follow up customer service. The faster cycling of a sight tracker or perfect sight gun is my favorite but I probably shot my Gans gun with plastic grip better than any of them. If you want a new nicer gun go for it. Just make sure it’s from a reputable source or build one up yourself if you can.
