Ask HN: What is your preferred domain registrar?

I'd really appreciate some recommendations for a good domain registrar. A few years ago I bought two domain names on Epik.com. I only chose them because a friend of mine had been using their services for a few years without issue, and had a referral code. Recently I've been really unimpressed with their lax security, poor management, and shady business practices. I'd like to move my domains to a new registrar, but I'm not sure who to choose. Any recommendations would be really appreciated!
