I prefer the Jetboil. I used an MSR Whisperlite for years. However, it cooks slower, is more complicated to assemble and start, and you have to carry gasoline. The Jetboil is SUPER easy to use.
Having said that, all these stoves do the job that you want them to do, more or less. I did have a problem with my MSR Whisperliteon one trip. It wouldn't light one night. Fortuantely I bumped into another backpacker the next morning who had a cleaning kit, specifically the wire burner cleaner tool. I think the fault was mine -- I used many years old (maybe 6 years old?) white gasoline, and the gasoline may have become corrupted over time. Gasoline is not stable over the long haul, meaning over several years.
