It does spatter a lot more, but after cleaning up the weld is more than adequate.

Its not that easy to use on car bodywork though as it tends to cut through .

IIUC on thin sheet gasless MIG wire is worse than MIG wire with seperate gas? - how so? Cheers Jim K

You can get differing ratios of argon, CO2 and O2 depending on thickness of material and depth of weld. I concede that the shielding gas is better than "gas" from gasless wire, but its effect can be offset by using a lower welding current.
