Servers from allwebhost.com and owned-networks.net are nice for me and I wonder which way is better to go and why?

It is a good idea to speak to web host's representative to make sure that you'll receive exactly what you need.
Like CentoServer.com - The host has the team of professionals who know how to keep their services on top and also offers some entrancing specials from time to time.

The mentioned companies -  allwebhost.com and owned-networks.net - are worth trying due to their top-notch services. No matter what time of day I have ever had to contact technical support with a query, they've always responded quickly and efficiently and never let me down,
 

I usually don't recommend but you should 100% go with ZipServers.com dedicated server hosting.
The best support team. Quick response, experts on Joomla and Wordpress, very welcoming, very efficient. They offer easy to use features.

Please, be more specific... I mean requirements: disk space, bandwidth, server location, budget?

I've been with 3v-host.com  for over a year. The Bitcoin Dedicated Server hosting service has been fairly good. Value for what I'm receiving is excellent.
The evening and weekend support a few months ago have given me a lot of confidence in their customer-focused approach.

Can also recommend Regvps.com - this host may be a bit more expensive, but the support is superb - usually less than 10 minutes for response and solution. For me, that cheerful, ungrudging support is priceless. I simply LOVE my host!
