Hey, I’ve never ridden or worked on the ghost, however looking at the design of it, I don’t think it will be as capable a frame as the trek.
My mate was here on friday with his 09 trek fuel ex8 and the design, build quality and weight of the bike is very impressive.
I agree about the bontrager components, they are quite crap, the wheels on the bike I serviced where badly buckled and the front bearings where ruined, why not buy a used frame from ebay and simply build it up with the parts that you want to run.
If it was my choice I would hands down go for the trek, upto you though and good luck choosing the right bike! 😀
