If JMAP is to be successful, having support in Thunderbird is a must have first step. It's not helpful if the same party that provides the mail service provides the frontend as well. In that case you might as well leave out the open protocol and just push the browser-based client.
I like Fastmail and use it because it provides a service, and does so well (which includes support you can actually reach out to and talk to a human who will actually help you). I also like that my identity and daily e-mail experience is in no way hard-linked to them. I have my own domain, and I use Thunderbird and K9-Mail (now also Thunderbird).
I also like that I can log onto to their website and do things there if needed. This is mostly managing masked e-mail addresses and the occasional check on my subscription settings.

And if you're going to fund development, also put it in Dovecot.
