This is a comparison that I made when I was testing different VPS / VDS providers using nench.sh server benchmark.
| Provider | CPU | SSD | NETWORK | 
|---|---|---|---|
| hetzner | highest | high | medium | 
| digitalocean | medium | high | highest | 
| scaleway | lowest | low | highest | 
| contabo | low | lowest | lowest | 
| arubacloud | low | highest | medium | 
| zomro | low | lowest | medium | 
| eurobyte | high | lowest | high | 
| friendhosting | medium | medium | lowest | 
It seems that contabo and zomro are obviously lying about using ssd servers. Arubacloud is not suitable for a long time high LA projects, they will just cut your VPS / VDS resources.

I ended up using 60$ dedicated server at hetzner but then I refactored my project and now I' am using 5$ VPS at digitalocean.
