I am using the new UI, and I haven't found it to be particularly slow. I like it, primarily for the ability to snooze. I wouldn't switch back to the classic version, although they took away that menu option for me a week or so ago so it's not like I could anyway. I too use Proton Mail, but I still have to use my Gmail and Google account for various things I don't have control over.
