VPS (shared resource) is always a risk, but I only ever had one problem where claimed specs were not really available runtime (SSDNODES). Netcup is decent so you should get what you pay for. But if your Cloudron is "production" (meaning you rely on it for services), I would go for something more dedicated resource.
My first destination is Hetzner Auctions.
Interestingly their auctions are cheaper than their shared-resource VPS currently. They're pinched on RAM etc costs, but auction is still cheaper than VPS. My current Hetzner production cloudron is cheaper (60 euro) with much better specs than their cheapest dedicated auction (75 euro). But I think it's an industry thing, rather than a Hetzner thing.
