I don't think there is much better than floorless. Like what was said earlier, being able to go right in with your boots on and not make a mess is awesome.
Site selection is everything for water, and having a little ground cloth or sheet of tyvek works great for sleeping pads, gear etc.
The half liner is also crucial for condensation in my area where it can be very wet. That combination along with the wood stove makes for a comfortable experience even in the nastiest conditions.
If bugs or little critters are an issue, a nest with bathtub floors should solve that just fine.
I can't speak highly enough on the quality of Seek Outsides gear. Very happy with the purchases I've made from them.
