I had never heard of Mailshell.
But if you look at their website, they have lots of "big names" that use their technology. Personally, I would rather do antispam at the server level instead of at the client level. I generally consider client-level antispam only when the mailserver doesn't support server level antispam without lots of machinations. If you are happy with Ninja, I personally would leave it.

From: Thomas Gonzalez Sent: Monday, December 08, 2008 10:58 AM To: MS-Exchange Admin Issues Subject: question on MailShell Since I am employed by a non-profit our vendor is providing free Mailshell licenses to our org. So my question is this: does anyone have experience or knowledge of Mailshell on the client side? We are currently using Ninja at the server level; which has done an excellent job and I have no complaints. But I would like to hear some of the lists view on the product.
