Just looked at big air, nice units and if the vent issue was key for you Big, that's good, but overall I think Vintage has a slightly better offering. Many of big air's options were standard on mine, I also preferred my (optional) electronic controls vs cable operated. I think vintage's units look shorter and wider which in general let them fit behind the dash better. I do like their vacuum operated compressor switch though, nice option I didn't see on Vintage site.

Old Air options electronics and manual controls. I opted for the manual knowing any breakdown I can repair.
