Classic Nexuiz was last updated in October 2009 and OpenArena's last two updates were in October 2008 and February 2010.
I think Warsow and Xonotic are the two best free and open source arena shooters of those listed, with Warsow more likely to please the UT fans and Xonotic more likely to please the Quake fans. I've always preferred Quake over UT when it comes to deathmatch, so my vote's for Xonotic.
Some day when we have a super-duper dedicated box to run as many game servers as we'd like, we could run both a Warsow and a Xonotic server and the people can choose (or play both).
For now, I'll probably turn on my Xonotic server (hosted on my elderly but functional desktop) if and when people want to play a few rounds of deathmatch with me.
