After trying dozens - classic pressure stoves, MSR and Primus modern offerings, my preference for zero hassle and everyday convenience is a Trangia with a gas burner fitted. About the same cost all in as a Jetboil full price. Fast, windproof, pots and pans all included, modern gasses OK to quite low temps. Assuming that is that you want something portable. Depleting cylinders are a bit of a pain with gas stoves, but the solution is as one cylinder gets a bit low, keep it for simmering and have another fresher one for fast boil.
You can always get a cheap gas burner that sits on top of a cylinder that will do the job for about £10-15, but you have to shield it from wind, it is relatively inefficient and you have to provide the pots. Depends on budget.
