The past few years I have used the JetBoil PCS.........but being a "weight weenie", as Aron would say, this last year I decided to try the new JetBoil SOL TI. Swung by REI on the way to the hills and used it on a weekend scouting trip. I was really disappointed with the inconsistency of the auto ignitor actually igniting the flame, especially since my older PCS lights the first click - every time!. Thinking I bought a lemon, I returned it to REI and exchanged it for another SOL TI.....same issue! Although the ignitor can be annoying, I am willing to put up with it for smaller size and 6 ounce reduction in my pack.
