I have a 14x20 Clopay 4300 series on my barn and have no complaints. Ended up putting the same doors on the house after I built the barn. I have a 14x20, 12x12, 8x16 and 9x8. No issues at all.
Mainly for ease of steel removal/replacement if I ever need to service a panel, but it's also a bit cheaper to top coat the XPS with only 1" of spray foam vs. 2-3" without the XPS. I got a good deal on the XPS though.
I was also warned about steel panel distortion without the XPS.
I installed 1.5" XPS foam between my girts for my first layer of insulation. As soon as it warms up in the spring, I'll be spraying an inch of spray foam over the XPS and girts to seal everything up. I didn't want to spray directly on the steel, so I did it this way. It was pretty tedious...
