Which is the most stable version of Ubuntu? [closed]

The latest versions marked as "stable" are always available from http://www.ubuntu.com/download/ubuntu/download

But, personally I prefer Debian over Ubuntu. Ubuntu is a Debian-based OS, but for me as a power user doesn't add that much useful features that I'm missing in Debian itself.

My understanding is that the LTS release should be more stable. There are less new features etc. in those releases. The current LTS release is 10.04 and the next will be 12.04.

According to the Ubuntu download page:

Our long-term support (LTS) releases are supported for three years on the desktop. Perfect for organisations that need more stability for larger deployments.
