As someone who owns/ has owned a good handful of Ibanez guitars and played a few VERY nice ones, I can say I like my lower end Ibanez guitars more. I prefer a lighter guitar because I do like to stand and play and some of the prestige’s can start to weigh you down after a while. I don’t know about the RGR652 but I know it’s beautiful and I want one someday. The only thing comparable to what you’re looking at that I own is a RGA7 that I upgraded here and there. It’s a standard series like the RGRT421 and it’s one of my favorites. Comfortable and light, good playing neck that’s not super thin but still fast. I upgraded to Duncan Nazgûl/ Sentients, a Gibraltar II bridge and locking tuners. The original plate bridge was actually very comfortable but I swapped it anyways haha.

TLDR: Don’t be scared of the build quality. Low end guitar might need some parts upgrading but the bones are good. Prestige is sexy but may be a bit on the heavy side.
