Why I love it:

• I love the UI. Quick, intuitive and good looking.
• Basic functions are good. The phone works well as a phone, with calls (including VoLTE for a number of newer models now), SMS, MMS, wifi hotspot ++ working
• The amount of native apps is pleasing to me. Of course, you won't get the usual proprietary big tech developed apps, but other basics are there.
• The flexibility is awesome. You can install apps from the Open Store built especially for UT, Snaps (not all of which are meant for small screens with touch input, but you get to try it and decide for yourself if you can make it work), nix packages, installing stuff in libertine containers, AND Android apps in a Waydroid container.
• The community is extremely helpful and diverse.
• The two previous points, community + flexibility, helps whenever you miss one of the larger apps. Miss Telegram? Meet the native app Teleports! Miss Signal? The community can give you several options. WhatsApp? Of course some generous soul has made a UT adapted web app that you can use in stead.
• I finally feel free. I own my device, and the software I run on it doesn't feel invading or dishonest.

What is sometimes difficult:

• I need to be honest about the browser situation. The default browser has a nice UI, but it is very outdated. There is a lot of improvements going on behind the scenes, but the new version is not ready for launch yet. The alternatives are UT adapted versions of Librewolf and Firefox, but they are both in an alpha state.
• VoLTE only works for some of the supported phones, and it is still considered experimental.
• Banking and ID verification apps have almost no UT native solutions, and running them in Waydroid is very hit and miss.
• General stability. There are more bugs and crashes here than in Android/iOS.
