Download/Distribution Recommendations

[CurtisJasper]

Now that the US release is officially available, I am going to be purchasing Armored Princess.

Based on results from the original KBTL, does anyone have a particular recommendation when it comes to the version of game to employ (retail, Steam, etc.)? I realize that in principle all of these are the same, but I seem to recall certain versions or distributions being buggier than others and seeing patches earlier/later.

Thanks in advance,
Curtis
