I have had good experiences with Proton. I pay for the business tier so that I can manage multiple domains… but that’s not your average setup.
Literally my only complaint is that the new-ish vanilla SMTP service does not play well with systems like DMA or Postfix, so I have issues using it for cron emails on my servers.
Everything else has worked pretty much perfectly since I migrated over.
Edit: I echo other commenters though, get your own domain regardless of where you host it. That way you can always pack up your toys and go somewhere else if required
