I own <initial><last name>.com and <first name><last name>.com and I'm paying for Fastmail, but I hesitate to give these addresses out widely. I can see many benefits to domain email but I don't want people to think this is just a vanity address, especially as I don't work in IT or have a business or website. I'm an accountant (not public facing) and I think my <initial><last name>@<well-known provider> actually looks more professional on my CV (although I wouldn't use it for actual work - I have my address at my employer for that).
