I tried Ubuntu Touch for about a week or two (absolutely broken on the OnePlus 5 btw.) I kind of had a VM of Android on it. I used Waydroid for apps I need, like E-Banking. Waydroid was an absolute mess, it constantly crashed and often played Music via Speaker instead of Bluetooth.
Edit: I really liked the way, how to interact with the whole os. The habit to switch apps and show the sidebar stuck with me for at least a month after my little experience.
