Which option would be preferable and why: comparing servers from HostSailor.com and HostingSource.com?

I can't say enough good about Webhost.pro solutions. It just isn't possible. I just totally love them!

Both hosting providers offer 24/7 support with knowledgeable and responsive operators who can quickly address any issues or questions that arise via ticket or chat.

Additionally, ASVhost.com and Planethoster.com are known for their fast server performance and impressive 100% uptime records.
Choosing between these two options may come down to specific features and requirements you have for your website or application, but either option is likely to provide a well-balanced solution with strong uptime and support.

I've been using GTHost instant server for about 10 months and I always have fast speed connection and my web site is steadily online.
The customer support is responsive and friendly - any problem is solved immediately. Uptime is good as my sites are always up.

Give vote for hostingsource.com server hosting. The pricing is very good, especially for what you buy for it.
They are really good to take care of their customers! I like their service and support.

Plans from hostsailor.com and hostingsource.com are full-featured and low cost.
I have found these guys very competent & dedicated. As far as the price is concerned, they are quite good in price & offering very cheap rates to customers with great response & services.

How many customers are on each server?

I tried different free cloud servers about four years ago, and then some providers of such services had an interesting feature — when resources were overspent (for example, processor time allocated for a trial), the account was not blocked, and a fee began to be charged for use.
Then there was a sensational story about a user who turned out to have to pay quite a considerable amount in the end.

I first contacted zakservers.com support staff for help with one of their packages, I could tell this host was a keeper.
The prices are outstanding, my hosting was set up immediately and accounts transferred almost as soon as I gave word. The support is outstanding.

Servers from asvhost.com and planethoster.com are nice to have a deal with.
I highly recommend them for your hosting needs. Besides the great customer service, they have super fast solid state servers - which is another plus for me!
