I've had to bounce around from Mac, Windows and Linux for work, the main programs I use everyday are all Electron based (Postman, VS Code, Spotify etc), they all behave basically the same just everything is slower in Windows on my laptop. Egui (immediate mode GUI) and Tauri (like Electron but Rust backend) have worked well cross platform just messing around with them, but I haven't used any big apps yet to know for sure.
