I'm using milestone 5 on my Nexus S 4G and I really like it. I was using build 31 on my TFP and felt that even with motley, the battery went much faster than it did on Virtuous Prime.
i just flashed mine last 2 days ago with build 38 (AOKP).. make my other games stable, like SHADOWGUN, TAPTAP revenge and others... happy with it... still hoping for more fixes and great tweaks/upgrades in the near future...
