I also manage a SharePoint team, so I'm not biased. It’s just my opinion based on what I see.
I've used and administered Confluence for the past three years, over five versions. I am about to upgrade to the sixth version.
With earlier versions, such as 5.4.4, we did have stability issues. After upgrading, we've been stable and fast.
Stability issues were caused by an increased user load, i.e., scalability.
Technical support gets a rating of 5/5. We pay for Premier support. It covers ALL Atlassian products. If these products are in any way important to your company, it's worth the cost.
We were using TWiki. We needed an enterprise ready tool instead of freeware.
The setup was straightforward and perfectly documented. Atlassian gives you a step-by-step guide. You would expect nothing less from a documentation platform.
Atlassian is dirt cheap when it comes to enterprise software. I would suggest limiting the number of plugins (a.k.a., add-ons), as they are an extra cost and many times you're dealing with third-party vendors.
At the very least, use the ones that say "Atlassian Verified" and "Supported".
We did not evaluate anything else that I know of.
