I am biased, as well, especially since I never considered the Santa Fe, but I will say a few things:
1. I drove in to test drive one of the first '14 FXT's around, expecting to hate the CVT. Not only did I find it acceptable, I found it to be very good and was surprised by how nice it was to drive.
I rent cars for 2-3 weeks per year, and sometimes get a CVT vehicle (usually a sentra or something budget,) and never really thought much of them. I didn't dislike them, but normally wouldn't prefer it to a manual tranny or a good slush box.
2. The thing moves. I had a 2.0T Escape for a week+ as a rental and, while it was also quick, it didn't feel nearly as nice as the Subaru. The turbo in the Subaru is also very audible and both it and the BPV when coming off full boost quickly add nicely to the aural experience.
I don't know what the Santa Fe has, but the twin-scroll in the FXT results in nearly instantaneous boost.
3. Handling is just ok, maybe par for the CUV course. Again, I was coming from an STI, so I wasn't expecting nearly the same level of grip, and what the FXT offers was good enough.
With that said, the ride is very comfortable, which was probably what they were looking for. As a comparison, the FXT feels more SUV like, while the Escape felt more car-like; both attributes were nice at different times.
4. The vehicle is very usable and comfortable, but the front seats are lacking in a big way. This was the single thing that nearly made me skip the buy when I was looking for a new AWD CUV. The seats are comfortable enough, and I've definitely gotten used to them, but the leg support just feel wrong, and I can't ever find the right spot.
I did drive it down to FL with little complaint from my wife and passengers, though. The front passenger seat sits unusually high and can't be adjusted for height, but you get used to it. The rear seats tilt back a little and were pretty comfortable, with tons of leg room. My lower back usually causes me issues on long drives, but it was the same or slightly better than I've experienced in the past, in the STI, Civic, and my old Legacy (which had very comfortable seats!)
5. X-mode is nice, if you need it. I don't know what kind of AWD system the Santa Fe has, but the Forester XT's is top-notch (for a system without LSD's or the ability to lock anything.) The displays for the system operation are nothing but gimmicky displays, but the system seemed to provide a little better get-up-and-go in the very slick winter we've had, even with the [censored] OEM Geolanders still installed.
I'm looking forward to seeing how she does with proper snow shoes on!
