Ask HN: Which domain provider/registrar do you recommend?

I've been using a domain registrar for the past five years. A friend recommended them to me back in the day.

Lately I'm sort of troubled by the poor quality of their service, poorly designed (and confusing) website and a series of issues that happened while managing the domains I own.

I wish to move my assets elsewhere so I'm wondering what other places are good to look at? What is recommended?
