I have the Stubby brand ones myself, but they are a bit bulky and cumbersome even with the notched cutout at the business end. They work, but if the bead is super tight or stubborn, they can be a bit difficult to get in between the rim and the tire bead for that last bite going on.
I used the No-Mar aluminum spoons this past week to change a few tires in Moab and they were probably the best spoons I've ever used. I need to order a set soon. You could scratch a rim with them if you got really ham-fisted, but short of that they seemed like they would get the job done without leaving marks all over your rims.
