Servers from planethoster.com and surfhosting.co are attractive for me and I wonder which way is better to go and why?

I'll give these cheap dedicated servers props, nobody will ever beat them price wise for what they offer.
As long as they stick to their guns on not overselling their servers, I don't think I'll ever be looking for a new web host.

A professional web site hosting provider must guarantee you a high level of uptime. It means that your website will always be accessible to your clients. A reliable web hosting services provider must do his best to avoid any malfunctions.

Server uptime 99.99% and support i rarely use it since i am a webmaster.
Highly recommend GTHost.com Chicago servers to anyone! Like this one: E5-2695v3, 64GB, 2x480GB SSD, 300M Unmetered starting at $99.

No hidden fees or surprises, very reliable service. Highly recommend Neironvps.com dedicated hosting service.
The price is outstanding for the features provided, but in a time when hosting is very competitive.
