I actually just went through this exact situation in the last month and I switched to LMDE6 on my 2-in-1 lenovo touch screen. Auto rotation didn't work right out the gate, but iio-sensor-proxy fixed that. In general, I've noticed that the touchscreen default setting for some apps (eg, firefox) treats touches as a mouse click, so rather than scrolling it would select text. But I've found this AskUbuntu fix worked for me. Been a good experience since then.
