Fire almost all of the time.  I do bring a small one burner stove in case I want quicker coffee or it is too wet to want to make a fire or too late and fire wood is scarce.
Fire in mid-summer is often too hot to stand near to cook.  I would say my fire cooks faster or as fast as a stove regarding boiling water; however trying to cook on a BWCA grate is not so easy...takes a long time to heat the grate up enough to really start cooking.  I put a flat rock under my fire to raise it closer to the grate and cut down on how big the fire has to be.  I might be the one you are cursing when you have to drag the rocks back out of the fire pit.   ;D  I also sometimes take an S hook of sturdy wire (coat hanger) and hang the pot from the grate and over the fire to get it closer to the heat.
It's nice to have a little smoke from the fire to hide in when the bugs are bad.
I don't soap my pots but I do wrap each one in a rag from an old sheet.  They still nest into a tidy package but don't make each other sooty or my pack.  When I get home I either just clean the inside and wrap in a fresh rag or if I really want them clean something like Zip-strip paint remover will take the black off pretty easily.
