My age old experiance with Champions was not good and many of the oldtimers I know hated them as well. I would be VERY reluctant to install one in anything, I do hear of those who love Champions these days so who knows.

Supposedly, the new spec Motorcrafts are a lot less likely to stick - they have changed the heat range to minimise carbon deposits. I feel that if you use the new Motorcrafts, and install them exactly as specified - with nickel antiseize on the ground sleeve - you should be okay, and you need to use top tier gas too. Honestly, I have heard of a few people not getting good results with the Champions.
If you have to use crap gas, or don't get it on the highway frequently to blow it out, I'd probably use the Champions and change them frequently. This can get expensive - they are 15 bucks apiece.

Yep, and you can make the taper nice and uniform by putting the plug in a drill motor, then sand away.

I just replaced my plugs, with a little over 100,000 miles. of course all 4 on drivers side broke. I orded the lisle tool and removed all 4 with no problem. I put the Autolites in mine. Runs great. I won't be waiting another 100,000 miles before the next change though.

I've installed two sets of Champions, and both trucks came back later with random misfires. They stay true to form in regards to their performance in anything other than lawnmowers and Mopars.
I hear NGK is working on a one piece 3V plug.
