For drinking:
-I started out with the stainless, surplus canteen cup. I still like it, but almost never use it.
-I replaced it with the SnowPeak Trek700 titanium cup, and never looked back. Holds almost exactly the same amount of liquid, weighs very little. Because of the particular alloy they use, you can drink(sip) from it when it has boiling fluid in it, unlike aluminum. Try to sip hot tea or coffee from your wife's aluminum pot. Badly burned lips if you don't put cloth tape on the lip of the pan.
For cooking:
-Started with the stainless Coleman 1qt. pot. Minimalist size, OK useability, and way too heavy.
-Went to various cheap aluminum pots. Light wt. was a plus, but they were never very handy. Ultimately did not like them.
-Went to EverNew 1.3L titanium pot. Now that's what I'm talkin bout! Light weight, durable, easy to cook with and handling qualities are nice.
-Became near terminally unpleasable, and so bought the titanium Trek 900 to match my Trek 700. Beause it is the same alloy as the 700, heat doesn't dissipate as rapidly through it as in my EverNew pot, and so you get blackish scorch marks directly above the burner on my SnowPeak Gigapower stove. I count this as ALMOST trivial, but it is an issue.
-So, I cast my eye on JetBoil system. When I picked up their 1.5L "group cooking system" pot, I realized that the flux ring is so large in diameter, that it would sit on my GigaPower butane stove, just fine. I checked in the store, and it fits on the Pocket Rocket stove too, and also sits above the MSR Dragonfly stove OK.
So I bought it. I've run it a few times with my Trangia alcohol burner and my GigaPower stove, and boil times are indeed very short. Works fine, and you do not actually need to buy the JetBoil stove, just to use the 1.5L pot.
Dunno how much faster it is than my plain bottomed titanium pots, but it is definately a lot faster. I used to be able to set a pot on to boil and turn my back to do few things. Now, it is so fast, that once you light a fire under it, you can't really turn your back on it. I think I boiled a liter of 60 degree water in 6 mins with my Trangia burner underneath. This is fast.
I plan on backpacking with it, and plan to be pleasantly surprised by the improved fuel economy.
