Both me and partner switching to Infomaniak (also Swiss), can recommend. Not E2E encrypted, but kMail is more usable than ProtonMail (also a lot cheaper on all levels).
Been using ProtonMail for 5 years but so annoying I can't propely search my emails because of the encryption, can't use standard IMAP without a proprietary connector, and their Drives/Docs suite is missing a lot of features.
