We almost bought an X-Trail, and only did not because we really do use the low range which the '06 Grand Vitara has. I too disliked the fact you have to buy the most expensive X-Trail to get the VDC/TC and side airbags. Just as I dislike the similar situation with the GV's low range and the least useful stuff for off-roading that's bundled with it. (automatic, 17" wheels) The triumph of the marketing departments over common sense.
To add to your considerations is that research is showing that VDC is reducing single-car rollovers and the resulting deaths by about 50%. In combination with the extra airbags, it makes it easier to put up with the leather seats and higher price.
The X-Trail's lockable AWD system is one of the best. The problem is that when it's locked, it's not much different from an old-fashioned on-demand 4x4. If you lose traction with two diagonally opposite wheels, such as when traversing a diagonal ditch, or both wheels on one side, such as when pulled over on a snowy shoulder, the two wheels with the least traction will spin, and you'll be dead in the water. (I've also heard you can overheat the X-Trail's center differential, causing it to revert to 2wd. I don't know if that happens when it's locked.)
If you had a limited slip rear differential, it would prevent this wheelspin scenario up to the point where the stress differences would make the rear differential slip. But it's far better than being without it, and reduces the need for traction control. Unfortunately you can't get a limited slip rear differential for the X-Trail.
So, it depends on your needs. I wouldn't have bought an X-Trail without shelling out for the model with VDC/TC. We were replacing an older Pathfinder with a well-scraped bottom and regular use of the low range. Australians are using the X-Trail for some impressive stuff, and one of them finished this year's Paris Dakar torture rally in 20th place overall.
Instead, for thousands less than the X-Trail LE, we got the Grand Vitara, with all the gizmos of the X-Trail LE plus the low range. If you don't rack up a lot of miles, you might keep the price down by buying a used LE. Might be hard to find one, however.
As for color, I think the X-Trail looks great except for the dark blue and black.
