My name is Ken and I'm a stoveaholic.
My three favourites.
My favourite stove is the Solo Stove Titan, pros- I love it, it burns biomass completely (leaves no trace) stays cool at the bottom so can be moved quite easily and is bomb proof, if I prepare the fuel properly 1 load will last maybe 45 mins (never properly timed). cons- it is very bulky doesn't fold down but you can store stuff in it easily just needs some thinking about.
My second favourite is my Wild Woodgas mkii, it's almost as good as the solo is more compact, gives great burn times, but it feels less stable, leaves a bit more mess. Once I make/ find a "brew kit" bag that will take it and my bottle/mug this will be my go to stove.
Recently I bought a Firebox, I've only played with it in the garden but I really like it. It's really versatile, can be used in multiple ways with multiple fuels, is really sturdy, easy to put up and take down, bombproof and folds flat. however it does fall a little on the heavy side and makes more mess/less controlled than the wood gas stoves. but saying that I think it would go with me because it's lovely having a controlled little bonfire/firebox.
To be honest though all my stoves are on the solid heavy side because I like stuff to last and enjoy having the confidence that they're going to hold up. weight and bulk is not a huge concern.
I also have a kelly kettle love it but only for car/canoe camping, a tentipi firebox again for car camping or beach bonfires. 3 different cheap wood gassifier clones that are for messing around with or loaning out, a grilliput barbecue set which is too heavy for what it is, some homemade hobo stoves I made years ago, a couple of attempts at gassifiers and a half made fan assisted rocket stove. I also spent some time messing around trying to make something that would slot together but I gave up because my attempts always felt really unstable and unsafe. (probably because of thin sheet metal and too wide slots)
