If you're fine with Wayland, go with Wayland. There are lots of reasons still that people might prefer X11 but the list has been getting shorter.
- The security model of Wayland is more restrictive than necessary for many users and means things like screen sharing and desktop toys are harder and not universally implemented or doable.
- Wayland effectively requires many things to be handled by the same process, preventing traditional modular environments (e.g. separating window manager from compositor no longer possible)
- Explicit compositor support required for more features, meaning having a feature complete environment in small projects is much harder, and the design of Wayland tends to promote a few large desktop environments rather than many small window managers.
- NVidia's support for Wayland is still improving
- Wayland can't rotate your screen to be on an angle to maximise the length of a line
- Several programs I rely on don't support Wayland well yet
- Steam doesn't stream from Wayland
- Transparent bits of FreeCAD show the background instead of what's behind them
- Code-OSS required a very silly workaround for decent font rendering, although I think this might have been fixed in electron
For what it's worth, I regularly switch depending on what I'm doing (AwesomeWM for X11 and Hyprland for Wayland)
