How about you guys put together a collection of an artisan, high end pipe, a quality meerschaum pipe, a clay pipe, a corncob, and a few middle of the road Petersons/Savs/Stanwells and send them to me. I'll tell you what's the best :D
In all honesty, though, I have a modest pipe collection that ranges from MM cobs to Yello-Boles all the way up to Dunhills and Ashtons. In my opinion, my cobs are suited for certain tobaccos and my briars are suited for all of my tobaccos. If I had to guess why that is, I'd say it's because I smoke my briars all the time and get a lot of practice on my technique. I don't smoke my cobs very often, therefore I don't get much practice packing them. I, like Cigrmaster find them to smoke hot and wet most of the time. However, my cobs seem to smoke Anni Kake better than any briar I have (but only when I can get over constantly sucking down tobacco condensation the whole time)
Also, let me apologize in advance for any typos or poor sentence structure. I'm on my tablet.
