Managed server from a decent provider

[Upiter]

Hostingsource.com and a2hosting.com provide quality and reliable manacved servers in a webmaster-friendly manner and I wonder which one is better to follow?
What would you do being in my place?

It seems to me that it will be reasonable to widen the range of your search. Try to look at http://m3server.com
PROMO CODE: M3HOST75OFF - It is good for 75% off first month on VPS, Dedicated, M3 CDN products.

I want to say that hostingsource.com as well as a2hosting.com are decent and reliable in delivering their services in a quality manner.
Support is active around the clock and prices are competitive.

It can never be stressed to highly enough that nowadays, cheap web hosting plans does not necessarily mean poor quality and service.

As for professional web host, can recommend centohost.com EU dedicated servers.
They have one click installs that you can install on your server with just one click of a button.
