I always use my Giga Power with Snow Peak fuel canisters. don't know if that makes a lot of difference but I never have any issues with the Giga Power. I use the Snow Peak windscreen and a fold up aluminum one. I can adjust the flame at will. Easy to use stove!
The brand of fuel generally shouldn't make any difference
unless you start getting into colder weather. If the temperature of the fuel (not the air temperature) falls below about 40F/5C, then the brand of fuel starts to matter. For temperatures where your fuel is going to get colder than about 40F/5C, pick a brand that is isobutane and propane only (no "regular" butane). In other words, don't get Coleman, Primus, Optimus, or Glowmaster brands. Instead get MSR, Brunton, Jetboil, or Snow Peak which do not contain "regular" butane.
