I've been using the crap out of my JetBoil SOL Ti this summer - both backpacking and for boiling coffee water when car camping (Starbucks Via, just too quick and easy w/the JB).
One aspect of it that I really appreciate, is just how crazy fuel efficient it is. I bought a Coleman 8 oz. cannister from Walmart when I first got the JB and have been using it all summer for making coffee while car camping (I drink a lot of coffee, and I do a lot of car camping...). I just got home last night from another five night trip, with lots of coffee making and that dang fuel cannister is STILL going!
On my recent five night Uintas BP trip, I used the JB for two people, two meals a day including multiple cups of coffee and hot chocolate each morning, fried fish in a big (borrowed) frying pan etc. For the whole trip it didn't even use one 8 oz. fuel cannister. For a two person, longer trip like that, the light weight of the SOL system combined with only having to carry one fuel cannister makes for an over all very light, compact package I think.
And of course it boils water just stupid fast, too - which is the biggest reason I switched to the JB/Via setup for my car camping coffee over the "coffee balls" method I'd been using for 25 years prior.
Anyway... I know very little about these stoves, actually, but have been five star happy/impressed with my JB SOL Ti.
