The Trail Designs products are sort of a darling, here on BPL. The Caldera Cone is liked because it is one of the more efficient alcohol setups. Also, a lot of people just think that it is inherently cool to have a windscreen that doubles as a pot support. The Ti versions are also incredibly versatile, burning alcohol, Esbit, or wood.
But probably most importantly, the Trail Designs skunkworks put a lot of R&D time into their 12-10 stove to ensure that it would work well in the widest possible spectrum of conditions, elevations, fuels, wind, etc. You can’t really say that of a Fancy Feast stove that you punched out in two minutes in your garage. And they now have the Kojin stove as an option but I’m not sure if they did as extensive of testing with it- they sort of marketed it quickly when everyone was clamoring for a Caldera Cone kit using the Staryte stove (to which some think the Kojin is suspiciously similar). EDIT– Russ says there was indeed a fair bit of R&D involved.
But the Caldera Cones are actually some of the heavier alcohol stove options out there. (The thing I find most intriguing about them is the multi-fuel wood burning option with the expensive titanium cones.) A Starlyte and a bit of aluminum for a windscreen would be quite user-friendly and a lighter option. The Starlyte (and Kojin) are also reasonably spill-proof.
BUT BEWARE! Everyone who starts using alcohol stoves eventually gets sucked into the black hole vortex of making their own. It gets addictive. I’m currently using a Fancy Feast stove with a bit of aluminum gutter flashing as a windscreen. Heck, I can make one almost anywhere by dumpster-diving, and it’s simple.
But where do you hike? If you’re out west then there will often be burn bans where you are hiking, so you may as well just optimize a light canister stove since you’ll be forced to use one most of the time anyway, in which case the MSR Pocket Rocket and the Kovea Spider are darlings here (for different uses). Despite what I said in the last paragraph, truth be told I’m actually usually using a canister stove for this exact reason.
