MrMonkey

It’s bad on Android, but is good on desktop

Correct, aliases are one of the best built-in features. Unlimited aliases costs covers a decent part of the subscription

If you are referring to ProtonMail encryption, i think it’s primarily about encryption at rest, so that nobody except you (not even Proton) can read your emails. Unlike other email providers (like Gmail) where the emails could be easily accessed by the email providers whenever they want/need to (like data for ads or legal orders from government etc). While not at rest (i.e., sending/receiving emails), emails between Proton and Gmail are on TLS unless it changed in recent years. If the email is password protected in which case Gmail cannot read the email until you open it with the password

ProtonMail has a free version which is enough for many. Every email you send or receive in Gmail is being collected as data by Google and i don’t want to give my personal data to Google

Brave has built-in ad blocking, so no need to worry about add-ons. And it’s familiar for Chrome users since it’s also based on Chromium open source

I was a Bitwarden user for 2yrs and recently moved away to ProtonPass. Primary reason for me was native mobile apps and email alias feature. Although it doesn’t have a web version yet (which is planned and would be coming in future), browser add-ons and native apps cover what I need and migration was mostly seamless as well
