What might be the best panel solution out of the three mentioned on a VPS plan with 30GBs of space and 512MBs of guaranteed RAM?
I'm thinking of getting it either from Serverpoint.com or Asmallorange.com.

Thank you for considering us. I think that your choice must be based on your experience first of all... your skills etc

cPanel 11 is VPS optimized I believe (of maybe they just put in a fancy logo haha)... but I don't think you can go wrong with ServerPoint.com... (even though I am a direct competitor lol)

I don't think that the control panels differ much from each other. As I see ServerPoint.com offers them a lot including Plesk.
@OP, what features are you interested in?

For users (or for people needing web-space eg. shared) cpanel is better and more easy to use than most others.

I was only here because my hosting company has canceled my account and I don't know of a forum for that, can you point to one ?

Well you're not really comparing comparable products - you cannot compare a Windows control panel (DotNetPanel) to *nix ones (cPanel, DirectAdmin) as you're faced with a more more important decision first: Windows or Linux.

Your choice here is at least partly down to personal preference, but my own opinion is that Linux is the better choice unless you have a specific need for Windows features (primarily ASP/.NET and MSSQL). Broadly speaking you will find Linux plans are cheaper (no expensive MS licencing required) and require less resources - in my experience a 512MB Linux VPS will be a lot more powerful than a 512MB Windows VPS.

Beyond that, there is usually a difference in price between the various control panel options - DirectAdmin is cheaper than cPanel for example, and Plesk is licenced a little differently as you have the option of domain-limited licences (cheaper than the unrestricted ones offered for cPanel/DA) as well as the unlimited one. However, price is obviously not your only (and shouldn't be your primary) concern!

I would agree with newneo's post and say that control panel functionality doesn't vary that much from one mature control panel to another. The differences are mainly in factors like:

• Stability / reliability
• Ease of administration (obviously related to the above, but also things like how flexible it is in allowing you to customise configurations, upgrade components independently of the panel etc.)
• Quality and consistency of the user interface
• API support from any billing software etc. you may wish to use with it

Everyone has a different opinion about which panel is "best" - usually it's based on the assumption that the panel they use is the best, and all others are rubbish (often without any experience of using the others!).

Out of the choices you've presented I'd be going for DirectAdmin - I've heard a lot of good things about it, and seen it myself firsthand (to a limited extent). cPanel gets good feedback from a significant number of fanboys, but overall there are some reliability and flexibility issues with it which make administration a pain - most of the good feedback about it comes from end-users/resellers who like its interface; although the default interface isn't (wasn't) so good, but the skinning opportunities it offers make up for this to some degree.

I have no experience with DotNetPanel, but before considering that I'd concentrate on deciding whether you need Windows hosting or not (as above)...

This is primarily because there is a large end-user base who are already familiar with cPanel, its terminology, and its ways - but the same is also true of the other major control panels such as Plesk and, to a lesser extent, DirectAdmin. In our experience we've seen a lot of customers moving from cPanel to Plesk, and subsequently providing highly positive feedback relating to the interface and ease-of-use.

The Web Hosting Forum seems like an appropriate place to me, but you should start a new thread about it instead of hijacking an existing one

@Neocarlos:
I think you are after Linux hosting, as neither Serverpoint.com, nor Asmallorange.com offer Windows hosting, it's actually coming soon on Serverpoint.com site.
There's a community forum for Dotnetpanel
http://forum.dotnetpanel.com/forums/

Choosing between Cpanel and DA, I also tend to go for the latter one
You may google a lot about it, this is one of the threads
