Fully understand, and the new x5 standard seats 'look' better than most. If you're comfortable in them then no problem, but my best advice is be sure before ordering. There's a reason most spec sport or comfort seats, and why they are so expensive. Lots of mechanics and padding in them. Got to help resale too. You'd have to discount against all the other f15's that have them. Personally resale is low priority. I want to live with this car for the next 7 years so it has to fit me and the family, I mention resale cos the seat price is clearly an irritant to you- they are pricey.

Ultimately comes down to personal priority based on past experience. I never even cared about seats in the past. It was engine, gearbox, sat nav, color, etc. then I experienced the 330 seats, lost $20k in 12 months, and now wouldn't buy a car without fully testing the seats again.
