Google Domains has a decent UX but I'm concerned Google might close down my account out of nowhere and leading to me losing my domains
There's little to no chance of GoDaddy moral crusading (I mean, look at them) and shutting down your account, or failing at the domain registrar business, and they give endless nag emails to ensure you don't lapse a domain. I let one lapse intentionally recently and have gotten about fifty emails about it.
My main advice though is to never register domains and host your site with the same company. As long as they're separate, migrating is relatively painless if you have issues. But companies with both your domain and your site can make leaving a pain in the rear.
Plus:
- no upselling, no nonsense
- text based interface
- quick and easy to use/renew/change/etc.
- privacy add-on is reasonably priced and easy to select
- competent, long track record, reliable
- supports 2FA
Minus:
- there may be cheaper ones out there, but not by much.
- I don't know how many oddball TLDs they support.
- If you like animations, eye candy, flashy IU, gradients, 3D elements popping out of the web page, JavaScript changing the page out from under you as you click and hover around, then you won't feel at home there.
