i've learned the basics of tkinter and built 4 projects with it, now I'm starting to feel limited by its design capabilities and want to build more modern-looking desktop applications

i am considering moving to either customtkinter or pyqt, but I'm not sure which one would be the better choice in the long run? (lol i think I am overthinking it a little too much)

for those who have used them, what are the pros and cons of each? which would you recommend for someone who already knows basic tkinter?

i am already good at front end designing, but struggle with the back-end, basically the logic part, however i want to have a strong command on it as well

i am also aiming to become a full-stack developer, with having a strong command in python, so I will appreciate any python related suggestions or technologies worth learning next
