What do Fedi people think about #Posteo email service?

What do Fedi people think about #Posteo email service? I'm pondering my choices in case of degoogling and finding a good email provider isn't easy.
Here's my criteria:
1) It's an email provider. Not everything-you-never-needed in one ugly unwieldy box and a stupid AI on the side.
2) I don't care about so called privacy and encryption, it's a marketing fad. These services are just huge targets for governmental blocking. So wherever you cool hackers are, I'm staying away. I want to be with common people. I don't want to be a collateral damage.
3) I don't care about Five Eyes, Nine Eyes, etc. Whatever I write on the Internet could be written on the wall, for everything else there is PGP.
4) I care about respectability and stability. So this service has to be in business for at least 10 years and not run by a group of enthusiasts.
5) POP3/IMAP support without restrictions.
So this leaves me with two options: #Fastmail and #Posteo
Fastmail is great, I used it in the past when it was twenty something dollars a year, but now it's too expensive. $5 a month and most features are overkill. 60Gb of space is ten times more than all my working documents combined.
Posteo is cheap and affordable, 2Gb is more than enough. But I don't really know if it's good and reliable.
Other sane alternatives are welcome, of course.
