Between F11 and F12, which would you choose?

[reg at dwf.com]

I have a half dozen machines updated to F11, and one to F12.
Im wondering if I should update the F11s to F12 or leave well enough alone.

I realize that the F11 distribution has reached a 'stable' status, and
the F12 distribution will probably take a couple more months to reach
that status, but would be interested in hearing what other users have
to say about the pair.
