Which VPS (hostround.com or black.host) is better to follow and why? 

On average, how much traffic do you expect each month? What's your hosting budget?
I would recommend them to anyone and also do as I build websites for people and often use GTHost.com cheap VPS.
It's great to see such group of motivated and efficient people.

Why not try Webhost.pro vps?
This truly appreciable web host will always be recommended to all those looking for genuine and reliable hosts.

VPS accounts from qhoster.com and inet.ws are worthwhile.
I am fascinated with excellent customer support. Both online chat anytime a day and fast and responsive support ticket system.

 

If I were you I would try to consider as many as possible various providers.
I recommend you to have a look at https://www.kvchosting.net/
They are the best SSD VPS provider.

I agree. I have been using kvchosting.net for 7 years. No problems at all. They are professionals.
