Kitty's my daily driver on Mac (when I'm not using eshell, anyway), but on the Windows side I am actually pretty damn impressed with Windows Terminal over WSL2. I don't even bother using graphical mode on emacs in WT/WSL, it is smooth as butter and super responsive in terminal mode and aside from using Linux, I'm actually preferring it as a dev environment to a Mac these days.
In fact, it feels like there's an ever-so-slight latency when on a Mac that Windows doesn't have. At first I put it down to the keyboard feel, but even using the same keeb it feels a bit more 'squishy' on the Mac.
