alt Hacker NewsWayland supports HDR, it's very easy to configure VRR, and it's fractional scaling (if implemented properly) is far superior to anything X11 can offer.
Furthermore, all of these options can be enabled individually on multiple screens on the same system and still offer a good mix-used environment. As someone who has been using HiDPI displays on Linux for the past 7 years, wayland was such a game changer for how my system works.
Fractional scaling for wayland is broken on a per app basis which feels strictly worse to me than it was before. Libre office currently is broken on wayland and works in x11
