Need a solid VPS Host

[Bileator]

Hello everyone,
I'm looking for a long term VPS host that's reliable and has a great customer support. 
By great customer support I mean getting a response within a few hours not waiting days to hear back. 
Below are minimum specs I will need for my projects although they can be altered but I think these are good starters.
30 gb+ disk space
1 TB+ bandwidth
2 gb Ram
2+ IP addresses
OS: not sure what is best to be honest
Do you know anything about Rockhoster.com and also GTHost.com virtual private servers? Are they reliable? What host is better?
Any recommendations of any kinds are very welcome.
Thank you all in advance

VPS plans from libertyvps.net and inet.ws are worth trying.
These companies do a great job at providing services. Price is great...service is great...expertise is great.
All is great with them.

If you value excellent service, advice and professional support don't look any further. Give GTHost.com vps hosting a chance - you won't regret it.
Intel Xeon processor family with NVMe drives with an essential performance fit to handle the business workload. They are optimized for high I/O performance and low latency.

Suffice it to say that these guys are setting new standards in web hosting and in my opinion are the model for what every other hosting provider should strive for.
I've been with GTHost.com vps hosting for 8 months and already I can tell I'm going to stick around for a while.

I like GTHost.com Ashburn vps hosting service. Support, has never failed me, always left with a problem solved.
Overall if you’re not completely satisfied with them, you’re not going to be happy anywhere else. They are optimized for high I/O performance and low latency.

Can't go wrong with Rockhoster.com kvm vps. Easy admin functionality, billing etc. Their pricing is quite cheap.
It is prompt, courteous and has continuously gone the extra mile to make sure everything is running smoothly.
