I had read somewhere that indoors, gas can't be beat. But if your welding outdoors, the wind could blow the shielding gas away, therefore with the flux core better welds. ??? Contaminated welds w/o gas?
I'm sure that's a possibility cause even if you have a fan blowing on you indoors while your trying to weld it can blow the shielding gas away and cause problems. You can crank up the gas pressure to overcome it to a point.
