Stealth I have Contabo 2 years VPS 4 core and 8GB ram, and it´s fine. Not fast like the DigitalOcean, but 5€ vs 50€ is brutal...
Yes, you're right.
Contabo has the best resources to price ratio.
There's a huge test we did with one of my Cyberpanel friends and Contabo only lags behind when it comes to network performance.
But when you compare with DO, Vultr, OVH servers of the same price, you get less than what Contabo offers.
The best of all is Hetzner. It outshines other expensive hosts out there with fancy packages like high frequency servers, commonly found on DO and Vultr. And it's cheaper too.
But for as long as your website is not serving over 5 million visitors for a blog and 100,000 visitors for ecommerce website, go with Contabo. It's value for money.
