My CZs seem to like the Federal 115 grain FMJ ammo I get at Walmart. Usually around $17 or $18 for the 100 round boxes. Accurate and reliable.
I've not shot any of the Geco, Maxtech, S&B, etc. Shot some Winchester and Remington and the CZs don't do as well with that as the Federal.
My newer M&P 2.0 5" does it's best with the Winchester Nato 124 grain FMJ. Beats out the Federal 115 grain and my 115 grain reloads that also do well in the CZs.
Guns are funny. I have no idea why the M&P does better with the dirty Winchester vs. the cleaner burning Federal and my reloads, but it does.
Guns are like that. A load that shoots/works well in one gun won't do as well as something else in a different gun.
With reloading, sometimes, you can find a load that works well in several guns. I can tell you that the loads that do well in my CZ 9MM and .40 S&W pistols don't do as well in my M&P pistols. Then again, the M&Ps don't do very well at all, compared to my CZs, when it comes to shooting small groups.
