Ya I mean everyone is different. The thing I'd keep in mind is auto-regulation and things like RPE are a tool, they aren't a "program". They are used as a tool to make sure training is in line with the intended stimulus you'd like to achieve. If it is something you've only recently started using I'd keep in mind it can take a bit to dial in the specifics, but to also not get too worried about it, at the end of the day it is used as a descriptor and to help with training decisions not something I'd try to get too worked up over.
That said if percentage based work is better for you or "clicks" with your mindset no problem sticking with what works for you. Just depends on the person, for some that may be the right path, whereas for me I've been down the auto-regulated rabbit hole for nearly a decade now because programs like 531 just didn't jive with my personal philosophies, preferences, recovery style, etc. Find what is your jam and stick to that if it is working.
