I've driven a Tesla but haven't used carplay yet. Personally, I found the Tesla UI to be confusing. Lots of settings weirdly hidden in the menus, no physical controls have been kind of annoying, and lots of important bits of info are not easily readable.
Things like ETA are shown in super tiny, low contrast font and lane guidance only shows up ~30s before you need to take your exit.
