Hostdime is not really known as a VPS host is why. It's a "me too" type of offer, while their main focus is shared and reseller hosting. You're not really going to find reviews on them as a result.
Futurehosting, on the other hand, is a decade-old VPS/dedicated hosting brand that's very respected in the industry. It's what you'd refer to as a "premium host". Not necessarily because of price, but because of the quality of their support, network, and hardware. We'd used them in the past for specific projects. They're right up their with
LiquidWeb or
EuroVPS.
The only reason we no longer use Futurehosting is because the VPS are Virtuozzo -- the old 2000s style of virtualization (along with OpenVZ). It's not modern. Xen, KVM and VMware is the modern method of a VM. These days, we simply prefer (and sometimes need, in the case of Windows) the newer VM methods.
WiredTree,
Knownhost and Futurehosting are some of the best Virtuozzo based hosts you'll find.
