Made the jump and couldn't be happier. One thing I noticed to keep in mind: Debian doesn't seem to be as proactive nor expansive as ununtu when it comes to security updates. I'm subscribed to both dsa and usn mailing lists and the updates conancal puts out are far more numerous and timely.

Also, debians unattended upgrades packages leaves a lot of packages unupdated by default.

Lastely, ubuntu releases have a well-defined and known life span. You know exacly what date support will end. Not so with Debian.

If you're like me and willing to deal with these shortcomings, then I highly recommend switching to Debian!
