Best is in the eye of the user. Some LP setups may be finicky once you pass 8000 ft in elevation (give or take a little) but being you are from IA and the max elevation for the whole state being under 1700ft, you dont have to worry about the LP issue at higher elevations unless you cross borders. The dual fuel is great since it can use white gas, av gas, and just general good ole petrol from your rig if shit really hits the fan. As you liked my post previously you know I like partner stove (ALOT) but still own several coleman dual fuels. I would take the partner over the coleman, but I always keep a Primus omnifuel in my GHB. That dam thing can run on vodka and diesel if needed. IE flexibility truly is the king of roost on the zombie apocalypse, but for good ole "works every time with out finicking too much" propane is it. But you will never hear a blues song strumb a cord about the propane blue flame. FYI fox outfitters makes a really nice folding grill that takes up little room in the chuck box (I have all 3 sizes, the medium size is great for the rig and seriously takes up the room of a few deck of card, check it ou) and I just bought in the last month a Titan solo stove and 1800 ml pot for backpacking this year. I have used it a few times and must say it is a decent little setup for using biomass. IE wood/ twigs/ bark/ etc from your explorations.
IE one will find that there is more options to shake a stick at but most are generally pretty cheap which allows one to experiment and find what it takes to make their chuck kit complete.
Its like the Ford vs Chevy vs Toyota argument. That is why I own a Nissan.
