I will recommend visual studio this time, I used to work with GCC in mingw the past, it's is indeed good and the most complete toolset (my game in itch was developed using mingw).
However, if you are working on windows nowadays I strongly recommend you switch to Visual studio for performance reasons, it's waay more optimized (specially if you use the latest C++20 feature set) and more importantly the debugger is infinitely more powerful, you can go back instructions, runtime recompile and more...
