I am very happy with my VPS in IONOS. I pay the cheapest plan though but i have had virtually no problems with them for 2 and a half years. I recieved a mail once for a downtime but happened at european night so i didn’t even noticed. Otherwise, the dashboard solved any problem i caused.

I only have a very few selfhosted services there due to the limitations of my plan, but they are essential to me and i would recommended you to try it. It’s 1€ + taxes a month, very affordable, but very limited in resources.

I’ve used ion for years for web hosting with no issue. Not sure how it would compare

I’ve had an IONOS VPS since January and have no complaints. I even rebuilt it at one point. I have a larger VPS for $20/mo.

I’ve heard mixed things about them, never used them though. Personally I used Digital Ocean for my VPS needs till I had a spare computer available, at which point I moved everything in house.

My personal preference is Linode and maybe Azure
