I’ve used bitwarden and mulvad for years. Recommend both without hesitation.

I’ve been using Tuta since 2016, on paid plan since 2019.

Outside a single longer outage early on I had nothing but good experience with their service. Granted, I only care about email and calendar (the only two products they have at the moment) but both work without any issues.

I heard they’re good and I have just recently created accounts for them.
