I did the same after getting tired of NC's DNS interface. I host a few client sites with Netlify[1] anyways and moving over to their DNS (NS1) has been a breath of fresh air. It is free but they do have some paid options and the is UI dead simple which should be a requirement. Feel fairly confident I can rely on them to not muck up DNS records as this is critical to mail systems, websites, etc.

Two years ago there was a moment where I was close to working for them too so I always try to use their products where I see fit. :)
