I have an older elite match in 9mm (large frame, bomar sights, but pre-rail) that I added henning's grips to to make the grip a little smaller. And I talked my shooting buddy into a cz-75 tacsport in 9mm. So I've shot them both a lot. I have about 650 in my gun and he has about 1300 in his. My gun is 85% the gun his is. Sights are pretty much equal, I actually like my grip more (the large checkered wood grips and awkward magwell of the 75TS don't do much for me) My trigger is maybe 3lbs, his is maybe 2, 2 and some change, and a little cleaner. Neither is as good as a tuned 1911 or revolver, but light years ahead of a double action or striker fired gun. I like the full length dust cover of the 75tsa lot, both cosmetically and for the extra weight out front. If I can ever find a used 75TS for 850 or less I will upgrade. $900 is a maybe. I shoot the 75ts just a little better. 1" 5 round groups at 10 yds as opposed to the 1.5-2" groups I shoot with the elite match. I am more likely to upgrade to a witness limited if I can find ones used to 750 than I am a 75ts.
Couple of throughts: the 75TS does not have adjustable sights, and I like the current production elite matches a lot less than the old ones. I am not a fan of the new sights or the rail at all. EAA finally fixed the magazine problem with 9mm about 3 years ago, and customer service is not as horrible as the internet makes it out to be, but it's not what I could call good. I would call it "barely acceptable if you stay on them and are patient"
