@ProfessorCode @Tutanota it’s entirely dependent on the use-case for me. When I do any online shopping, for example, I use simplelogin so I’m not giving out my real email to companies. When I’m interacting with my bank, apartment complex, job, etc, I use one of my tutanota aliases as that allows me set up better sorting rules for when I receive important/semi-important emails.

It’s worth noting that tutanota’s aliases are permanent and simplelogin aliases can be deleted at-will
