Tutanota / Mailbox.org? - eviltoast

Hi guys!

I’m looking for a Proton alternative. So far I’ve seen these two recommended. I was wondering what are the pros/cons of each? Seems Tutanota offers more bang for the buck in mailbox size etc, but I’m not sure. I’d also like to have a better integration with Android, because Proton’s email/calendar apps suck big time.

Thanks!
