Floorless all day, and that's with a lot of Western Washington use. It's nice to be able to just walk into your tent and worry about getting a floor all dirty before removing your boots.
A lot of these issues listed, aside from possible rodents is just site selection. If it's real wet, say out on the Peninsula, a half liner was absolutely necessary even with the stove I was running.
I have nothing against a full tent, I've just grown real comfortable with the flourless setups.
