My current observations:

cPANEL:
Great to offer to people who aren't as technical, people who rely on a million inbuilt features that they will most probably never use anyway.
Looks nice with its great eye candy.
Is a little unstable, more possibilities for vulnerabilities as it comes with too many open-source packages.

Best use: For SHARED hosting (satisfy the user).

PLESK:
Very stable, supports FreeBSD and Linux.
Great for large networks, very practical for the administrator.
In relation to security, it is tighter, there are barely any vulnerabilities publicly available for PLESK itself.
(The daemons it runs is another issue).
Secure and Stable, perfect for people who don't require extra features etc. such as SERIOUS Businesses.

Server performs much better with PLESK, you could fit up to 1500 users on ONE Dual Xeon 2.4 Ghz (4 GB RAM) machine.

ENSIM:
Difficult to say with this one really ... it does not support BSD,
which is a bit of a problem. However, it runs very well on Linux machines, specifically FEDORA and REDHAT.
I think this would also be similar to cPANEL, being a good system for SHARED HOSTING.

Do any of you have more INDEPTH detail as to
what FTP DAEMONS and MAIL DAEMONS these use ?

Have any of you been able to CHANGE those daemons AND PROPERLY configure them so that you cuold ADD/MODIFY accounts through THE interface or AN interface ?

Also one more thing - in PLESK, the RESELLER account is the 'client' but what if your NORMAL USER accounts for DOMAINS wants a 2nd DOMAIN ? They're only allowed ONE, being site owner of it.
So PLESK RESELLER and PLESK MULTIPLE DOMAIN USER are using the SAME interface ? (PLESK CLIENT)

Plesk is my native panel now, i love it! SO nice, small, secure :)

I was using Plesk but these days on some of my machines I use CPanel. My customers love it. It is user friendly and have great features. I love it beacuse it customizable

I've found that 90% of customers want CPANEL. A lot aren't even aware that there are other solutions available.

Customers want CPanel, most of them and all its features. With proper care security on CPanel servers is achievable and can be maintained. And if so, why not give people what they want? :)

I have no idea what customers want. I know they want hosting and we offer Plesk and have alot of clients. How can you say you know what customers want? Do you know all the customers in the world? ;)

You should have an idea what customers want. If you do, you'll have more of them, isn't that what most businesses need? ;)
I can say I know what customers want with more or less certainty, otherwise it would be a blind-walk. Not knowing what customers want leads to business failures, this is an important aspect and should be taken into account when planning any business, don't you think?

Okay, I'll tell Plesk to stop development of their software because customers don't want it. Damn, and I just turned down half a mill for HostNexus. Oh well, live and learn. ;)

No need to start a flamewar and "i have x customers" contest.

Let people have varying opinions.

Yeah, it's never late to learn, will be a hard lesson for you, eh? ;)

Yea, I'm totally gutted by the revelations in this thread. What am I doing with my life? :(

The wise learn from their mistakes. The good news is you still have a chance. Don't miss it! :)

Hey nexdog I wrote you 2 emails - did your spam filter delete it again ?

Yah, I got them and will respond when I have a spare 30 minutes. Time is money. ;)

To get back on track here.....

Another control panel to consider which was not mentioned is Direct Admin.

This CP is Linux/FreeBSD compatible with a intuitive GUI which your clients will have a easy time navigating. The CP is skinable and there is also a 3rd party addon similar to Fantasico. Affordable for the host and is stable and easy to upgrade.

My experience with Ensim.

Ensim keep releasing upgrades, and each upgrade break something which need to be fix again with many more patches releases. So be prepared to arm yourself with sendmail, httpd (apache) configuration knowledge. Ensim is secure, sometime over secure for the wrong reason, as you admin your client's domain name, you have to leave the admin screen. So you cannot backup to admin another domain name. Tedious if you have to manage many domain names.

I have a daul Xeon 2G Ram 73G SCSI, it freeze when running Ensim and MailScanner with Spamassassin. And I have only 150 clients on it. I have to turn off spamassassin, re-config MailScanner, sendmail and httpd to get the server to stablized.

I am moving to Plesk.

Hrm ...

That is pretty interesting.
