I recommend Gandi. They support almost all the TLDs, their web UI is very decent, their support is excellent and they live up to their "No bullshit" motto. They are also overall good guys, donate to the EFF, took public stances against sopa and such...

They're a bit more expensive when it comes to domains but we're talking single dollars a year here.

Name.com has been legit for me for about 10 years. Use code PRIVACYPLEASE for free whois privacy (this code has worked for the past ~5 years). I've also used IWantMyName for some TLDs that name.com didn't have and I liked that they had 2FA, but overall it was much less polished.

I've used joker.com for years. The website isn't pretty, but you can actually do many functions via pgp email.

Ah, just Amazon (which uses Gandi under the hood.)

Many pluses: predictable, can be administered using the AWS CLI, consolidated billing with other AWS services. Heck, can even register domains from the CLI.

Only downside as others have pointed out is that Gandi doesn't make it at all easy to hide your name or company contact information.

I've been using Moniker for ages. I'm always surprised I don't see it recommended more often. They seem very steady and reliable.

What about Google domains?
