Two decent choices …

Cloudflare - honestly probably the best. No, you will not save money. But you get the single best DNS / Cloud Firewall combination in the world.

Enom - Again, not about saving money. The UI is dated … but the sub account options works well for the “family and friends” thing so that you are not on the hook for renewing THEIR crap. You can keep your stuff your stuff and their stuff their stuff.
