I feel like a few more questions are valuable when trying to buy a stove, because I've spent a ton of money on stoves over the years and always found situations where they didn't work.
First thing to consider is where are you using the stove?
If you do not plan on high altitude, with a focus on North America, then any propane stove will work. However, if you plan on travelling outside North America, you'll want to be sure that you can get propane at your chosen destination. I understand big bottles can be filled in a lot of places these days, but it's not nearly as common outside NA; we are used to every gas station having a propane cage but that's not the case elsewhere. Isobutane is a better option internationally if there are name-brand camping stores (these are the little tins favoured by JetBoil). The are also small, last a long time, and it's conceivable you can bring enough for your whole journey if it's only a month or less. But the only fuel you can absolutely get everywhere in the world is Diesel/Unleaded Gas, so a stove that works on that fuel might be your best choice if you plan on longer term international trips.
Second thing to consider is when will I be using it? Or more specifically, will you be using it in cold weather. If you are, then propane and isobutane (even the Winter mix) are not going to be very effective.
Third thing is: How much space/weight do I have for this thing? If you are Overlanding in a 2 door TJ for example, maybe you don't have a ton of space/payload to spare on a bigger two burner stove, in which case something small might be preferred.
In other words -- buy the best stove for your use case; do not buy a stove because it's used by a ton of other people unless they also have a similar use case to yours. To generalize a few use cases:
If you need something small and light, that will work in the cold and in high altitude, everywhere in the world, check out the MSR Whisperlight International. It can run on white gas, Kero, unleaded gas, isobutane, and more just by swapping the jets, which are all included. However, it's only one burner. But, given it can work anywhere and it's small, it's great for people who want a compact stove that is lightweight and can fit into a tiny part of your chuck box. I'd say this is the perfect solution if all you are doing is boil-in-bag, morning coffee, oatmeal, and other basic meals, with the occasional meal over the fire for special occasions.
If internationality isn't a problem, and you are primarily a low altitude/warm weather overlander, but you still want something that is small and compact, check out the MSR Pocket Rocket or the Jetboil system. Both are excellent.
If you need something that will work in the cold and high altitude, everywhere in the world, it's hard to beat the Coleman 425 (it's what we have settled on). It'll run on gas, kero, diesel, and many other types of liquid fuels. And, with a generator adapter, you can run them off Propane too. With the 425, we only need to bring one fuel type for everything -- the same gas that runs the truck and motorbike also runs our stove.
If you are needing a two burner, are OK with propane, then it's hard to beat the Partner stove quality, but it's easy to beat the Partner value for money with a Coleman propane stove or the Campchef Everest which has been highly recommended. Basically, comparing propane stoves comes down to wind deflection, BTUs of the burner, and overall build quality.
