Vultr is goated, I've been using them since ~2020 and have never had any issues. I stopped a year or so back and recently went through the whole onboarding process again and it was dead simple even 6 years later, with barely any price increase compared to other providers. Hetzner will always be the worst to me because plainly their UX sucks; I can't imagine if I was a non-technical user trying to use it
