I have an
18" two burner Partner Steel / Cook Partner stove for truck camping. It's an excellent stove, but I wouldn't pay today's prices for one. I usually use a 1/4" thick aluminum Partner Steel griddle with the stove, and add a layer of non-stick oven grade foil to the cook surface for easy clean up.
I have two JetBoils that I used for backpacking. The original JetBoil is now part of the truck camping kitchen. I still use it for boiling water for beverages and rehydrating or heating side dishes to go along with whatever is being prepared on the Partner Steel stove. I bought the second JetBoil Sol Ti to cut weight from my backpacking kit, but now I use the titanium cup with a different stove.
Like
Yinzer Moto, I use a very small canister stove for backpacking (and now moto-camping), a
BRS-3000T. It's titanium and weighs 25g, yet still has decent flame regulation and is efficient when paired with the titanium JetBoil pot. At $25, it's hard to believe such a good stove is so light and cheap. A rare find, easily paired with a lightweight pot:

I bought the stove as part of
a kit designed round the use of that pot. It includes some titanium foil to better integrate the stove with the pot, and a flat carbon fiber lid to further reduce weight.
I wish Ruta Locura still sold the kit, but JetBoil no longer sells the titanium pot because people were overheating them and destroying the flux ring. I've used the BRS-3000T with other pans and it works well, but it benefits from wind protection even more without a flux ring on the pot. I don't recall the weight for the entire cook system, but it's only a few ounces total.
