which version of the ssh daemon is more secure?

[Anonymous <cripto@ecn.org>]

I'm running an "unstable" system and I need remote access by
ssh. "Stable" is considered better for servers (but I need
unstable for newer versions of a lot of packages on my
workstation), "testing" gets security updates last, but
"unstable" has a higher version number of ssh. it safer to
run the stable ssh (1:3.4p1-1.woody.3) or the unstable one
(1:3.8.1p1-8)?

Thank you.
