In either case, I don’t have any horror stories. But I can recommend Hover. To be fair, I really don’t do anything beyond the basics with my registrar. I have 3 domains. One points to a GitHub pages destination. The second simply redirects to the first. And the third is configured as my email domain on Fastmail. But in the 5+ years I’ve been using Hover for those domains, I’ve never had any issues. And renewals are always made known way in advance with many reminders.
