You said it best when you said "YMMV"....because their is nothing more true. I can eat a bag of Russel Stovers PB cups every single day and probably still lose weight. The sugar alcohols DO NOT stall me one bit. However, they do give me explosive gas and cramps! So for that reason I choose not to consume them.

Some people I have read about would be just as well off eating regular peanut butter cups, because the sugar alcohols ahve the same exact effect as real sugar on them. So my advice is to experiment with your body. If you can consume them and still lose weight, then more power to you!
