I'm considering moving; Rackspace has pretty good hosted email for $2/user/month. We use it at work - webmail is acceptable though nothing to write home about, and their IMAP implementation is solid so you can just use a client.
But you pay $480/year for 8 email addresses? Ouch.
I have received exceptional support over the years, including them calling me twice when I reported an issue. My account is worth $5/month and I live in Fiji.
I've had to contact support a few times in the last few months for coworkers email issues. We're a very small company paying $5 per month.

If you look at the terms for G Suite (the paid business product), that is a top selling point. Businesses who pay for G Suite don't want Google using their data for anything, and Google complies.
Edit: in response to comment below, here are the main docs describing, including the Data Processing Amendment:

EDIT:
I think these are the terms and I don't seem to see this guarantee, but IANAL
