The Ubuntu guys would maintain 3.2 up to 2017 [1]

This means that 3.0.y would be maintained by Greg until 2014 and Debian
probably would have to support Wheezy more long than that, because when
Wheezy-next becomes stable (2014+) we will have to support wheezy
(old-stable) for one year more at least. So in the end the support for
Wheezy will end probably in [2015-2016]

Meanwhile 3.2 will be maintained until 2017 by the Ubuntu folks (they
support LTS releases up to 5 years)

Actually 2.6.32.y will be maintained by Ubuntu until 2015 [1] since they
need to keep with it up to that date. (2.6.32 was the kernel for Ubuntu
10.04 LTS)

So my humble opinion, as user, is that 3.2 seems the best choice. Also,
it is a newer kernel than 3.0, and this generally means more features
and better support for newer devices.
