Stable server provider ... what should I do?

[Ships]

Comparing servers from qhoster.com and hostsailor.com, which way should I go and why?

[Yohanesburg]

I'd draw your attention to deals from reliable server providers: hostingsource.com (https://hostingsource.com/dedicated-servers-promo/) (dedicated promo is 50% discount for the first month for all Server plans) and legionbox.com (https://legionbox.com/dedicated-servers/).
So I could say that I've never experienced better features, functionality, up-time, and support - tech, billing & customer - than what I receive at them.
