Believe it or not the CK tool is actually really well made and thought out. It fits better than any other I have used. i currently have and use about 5 different tools for BB cups. The CK became my recent favorite.
Doesn't surprise me one bit. CK makes good stuff. I know what you mean about having to push in the whole time with the Park tool. That's why got scratched. The stupid thing moves around too much and even when I try pushing in the whole time it still wants to slip away from the cup every now and then.
