I transferred from GoDaddy a few years back. I got tired of the constant attempts to up-sell me for services I didn't want. I went to namecheap and have been happy with their services so far. The UI is clear and pretty easy to use. They also support MFA for added security (GoDaddy did not at that time).

I've been playing with cloudflare recently, and just realized they also do domain registration and DNS hosting. I might seriously look at switching to them depending on hassle and potential benefit. But I usually like having dedicated registrar/DNS that is uncoupled from hosting.
