i have x75 with options i like. i have done quiet a few 200+ mile trips in a day so far. have 3000 miles on it @ 330+ wh/mi. haven't faced range issue so far (worst case i had 20 mi range left when i reached back home). couple of trips over 250 miles, i had to stop at a SC for 10 to 15 minutes, it wasn't so bad or way out of the way. x100 came after i ordered x75, between x75 & x90, i chose x75 with options. knowing my driving needs i chose color, seat config, weather, leather, towing, eap etc.
yes, range is king if you do frequent long distance road trips and dont want to stop for charging frequently. having said that everyone has different need.
