I need your advice ... help me please to make a right choice ...

I need your advice in terms of buying a right VPS for hosting a blog and two hosts are in my mind: justvps.pro and inet.ws, so which way is better tp go and why? What do you think?

These are comparable and there's multiple similar VPS providers available in the market.

I always recommend to check if one understands the specifications and conditions entirely, before signing up, and beware of trial periods and small print.
Many of these VPS providers will offer special deals only to lock you into a long-term / notably more expensive contract.

If you'd prefer straightforward pricing, guaranteed up-time, and no auto-renewing contracts - feel free to check what's available in the online store at MojoHost
This is primarily suited for multi-server and a slightly more complex hosting needs - you can, however, start with your own dedicated server already at $39 / month,

If your needs grow along with the traffic that your site gets, there's your safe bet.

Could you provide more details such as budget, preferred control panel, and server location?

That will help others give better suggestions. I also know Ayksolutions.com is a reliable vps hosting option. 

One of the few hosts that actually delivers on their promises: Simple control panel. Easy to manage. No technical skills required!
