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
