Vultr is underrated too. I've had nothing but positive tech support experiences with them. Their weird branding turns people off but they do not seem fly by night. We have used them for various things for years with very few problems.
I've dealt with many Vultr instances on behalf of my clients, and I've had nothing but negative experiences with them. Unstable performance even on top-tier plans. Internal network issues that support keeps trying to blame their customer for. Nowadays when I find that a new or prospective client has been using Vultr, the first thing I recommend is to move off of Vultr.
When there's an issue with Linode's platform, they discover it before I do and open a ticket to let me know they're working on it. When there's an issue with Vultr, the burden of proof seems to be on me to convince them that it's their problem not mine.
I've had interesting issues automating deployment to the point that my current build script provisions 9 VMs, benchmarks them and shuts down the worst performing 6. Some of their co-location is CPU stressed.
