Best constellation?

I was outside in my suburban backyard last night with two friends, using my 8" f/7 dob, another using a 55mm fluorite refractor. It was an enjoyable evening talking about the sky, observing trips, equipment and so on.

I had once jokingly stated to one friend that Ophiuchus was the greatest constellation in the sky, with more of a wealth of objects for observing than any other. Dark nebula, galaxies, outstanding double/multiple stars, loads of globular clusters, several Messier objects, planets crossing through it.... yep, I said, old Oaf has it all....

Last night, looking up at the Milky Way, one friend started needling me again about that comment. So, I thought I'd ask the question here....

For the average observer, not you guys out in Arizona with 30" buckets and mag 8 seeing, but the rest of us who get out to semi-dark skies on a semi-regular basis.... what constellation do you feel has the most to offer for an evening's observing. I am interested not in just quantity, but variety.
