Is Vultr any good?

I have been using them for couple years, i would highly recommend them.

Solid Technical support !!!

This solely depends on what good means to you. It's not a question that can be answered by yes, because it may not suit your needs. In 12 months have all my VMs stayed up - yes When I log a support ticket do I get a quick answer - yes Do they allow me to build with Terraform - yes Are they perfect - No If you could follow up with maybe what you are looking to do, I can give a more succinct answer

Such a generic question can hardly be answered fairly. Yes, VULTR is a pretty good cloud hosting platform, and pretty reputable too.
