I've been running my stove for a few weeks this year, and having burned a good number of bags of FSU's, Chows, Nature's Own, and TSC MWP's, I have to say the MWP's have burned the best by a long shot----good heat and very little ash. On the other side of the spectrum for me has been the FSU's--they've continuously produced crispy ash cakes in my pot. I know some folks swear by them, but they've not been great for me--I even bought bags from different stores, but still came away with the same results.
