5-seater does not haver an extra AC unit for rear air. they share the blower from the front. I remember reading about this a while back when I was deciding on 5 or 7 for my '22 pre-facelift.
The 6 seater has the advantage of the middle row for access to the 3rd row, with the extra spacing, also makes the 3rd row move livable for adults by sticking their feet down the center aisle. Also I like all the extra space to store things inside with the captains' chair config.
However, everybody is correct, in that, you cannot fold flat, so wider and longer items cannot fit inside. Gotta decide on what's more important. I didn't have a choice on seat configuration since I ordered the Plaid. I love my 5-seater when I had it. I don't really need the extra 3rd row, so 5-seater was perfect. Usually it's just wife and I doing long drives in the X. cost less, more practical. Would have kept it if the trade-in wasn't so damn good last year.
