I personally just purchased a maxed-out MBA. I went with the MBA because I prefer the form-factor and don't want the touch bar. If I'd been willing to accept those, I would've gone with the four-port MBP. At no point did the two-port MBP make any sense to me.
Edit: it's $200 to upgrade the RAM in the MBA as well. I wonder why the MBP was only $100 in the first place.
