Ubuntu Touch so far has the best hardware compatibility for things like camera and battery life. But it also insists on doing a lot of its own thing like using Mir instead of X and click packages. Running programs inside Libertine often crashes for me and is cumbersome. It makes developing for it harder. clickable needs Docker installed just so you can build and run your own apps on the device! Instead of letting you launch things quickly from terminal.

It make some things that should be easy on Linux harder. I.e., there's no Firefox + mobile tweaks like other linux mobile OSes, in part because it wants you to use Morphic.

But other linux mobile OSes dropped support for Halium/libhybris and even the very few that still have it don't seem to match Ubuntu Touch's level of hardware support.
