I've never shot the clones but I have the SP01 tactical and love it. Smooth trigger and extremely accurate. I did swap the grips for the Hogue with the finger grooves but other than that it's still stock. I think you'd be happy with it.
The Tristars are/were made by Canik and are one of the best clones out there. The SP-01 is genuine CZ excellence, but your clones are close quality.
Treat yourself and get the SP-01, but definitely consider keeping the Tristars as well.
