I've been shopping around for either the CZ75TS or the Witness Elite Limited and have found that the CZ tends to hover around $100-150 more than the Witness. Now I really love my CZ SP01 that I shoot in Production division, but I like that the Witness Limited is available in a wider variety of calibers, comes with adjustable sights, an aluminum magwell (the CZ is a small plastic one, but Angus can get you a good aluminum one for it), and is pretty much ready to run for what I want for Limited division. The downside to the Witness Elites is that they only come with one magazine, so you'll have a greater investment post purchase to get ready for any kind of serious shooting. I'm not sure how many magazines come with the CZ75TS, but I'm sure you get more than one. Also, I've heard that the TS has a better "out of the box" trigger.
I compared the Witness Limited rather than the Witness Match, because the Limited variant is much closer to the CZ75TS than the Match is. I own a Witness Elite Match in .38super and it's a wonderful pistol, but even with a .40smith or 10mm top end, it's not what I'd want in a pistol for Limited division. It does have adjustable sights, comes in a wide variety of calibers, and has a very nice SA trigger, but it doesn't have the full length dust cover or the magwell. The upside to the Match is that you can find them for around $500, which is around $300 less than the Limited (and $400-450 less than the CZ75TS).
All 3 pistols are very nice, high quality, competition type pistols...and all 3 might take a little fine tuning to run at 99.9% reliability for competition type uses. Any of the 3 would serve you well. What I will end up doing, more than likely is replacing the firing pin on my Elite Match (with an EGW one) and then selling it to purchase an Elite Limited in 10mm.
