I own an STI Executive and the CZ75 TS .40, but I compete in Open with an STI Trubor. I prefer the STI Exec only because I am familiar with the platform. The CZ is very accurate and has an excellent trigger. It is heavier than the STI and ergonomically quite different. I think the safety could be wider but other than that, at the price it should be everybody's first choice for Standard.
