I've been pretty happy with Mailbox.org. The web interface isn't great compared to Gmail, but I prefer Thunderbird anyway for normal usage. They used to have a weird 2FA setup, but they've since switched to the same kind everybody else use, thankfully.

Microsoft's been a bit annoying, since some emails I've sent to @hotmail.com domains go to spam, but at least they do arrive and aren't just bounced, as I've heard from some horror stories. Sending to @gmail.com accounts seems to work perfectly though. I don't send a lot of outgoing mail from my personal account anyway, so it doesn't really matter in the end. Some mails seem to take longer to arrive, but I had that problem on Gmail too, so I don't think there's anything actually wrong per se.
