I’ve found the number of the days feels much more than the years, and has greater impact, even though it’s all equivalent.

If you have got a Nvidia video card and you want to use it, use X11. Other than that use Wayland unless you encounter any bug or incompatibility.

Wayland is more modern and actively receives updates and features.
