I have to admit, I really like the idea of no bugs. A tent does that very well. My son and I tried using a tent like a tarp shelter a few weeks ago and it was a nice compromise, BUT it was still May and the bugs weren't bad yet.
We're currently looking for a new, smaller, lighter, more portagable 2-man or 2 X 1-man.
Hey! Maybe I'm not on the fence after all. We're going for tents! But we're keeping the tarps too so I'll have to get back to you with my vote.
