"Worth" is up to the individual. Proving something to be reliable over something else is kind of a hard task. No machine is guaranteed to be failure free. Even Wilsons have had to go back for work, but I would wager the frequency of of it being much less than some other 1911 makers.
The high end 1911s are for connoisseurs or those that appreciate/desire a more hand-fitted gun.
The Wilson will come with better magazines and their Armortuff finish is a very durable finish should you choose that option, but plain stainless is nice as well. If I had to choose between one of the two, I would choose Wilson. While I don't have a CQB, we have a a Professional Bobtail and have been much more happy with it than the four Kimbers we've had over time. It's been the epitome of reliability, but I can say the same about my Les Baer which costs a little less.
