I have been on Mac for years and don't use it for gaming. However, one thing I'll mention is it can now run the Switch really well with a native version of Ryujinx, I hear this is due to the fact that Apple silicone has an ARM based cpu and does not need to emulate game code. I've had pretty good success with Mario Wonder and even TotK (at 60 FPS) on my M2 Max. You will want plenty of RAM for that type of "emulation".
I would only recommend a Mac if you are more into productivity and want a few games as well.
