Not spent enough time in the 242 to really compare it to the 'dog, but the location of the swich panel down low almost between the rudders (it seemed) meant you needed arms like a chimpanzee to reach them when tightly strapped in - at least if you're a 6 footer like me! Perhaps not a problem for
WWW. The 'dog is a better designed cockpit in my opinion, far more ergonomic and well thought out.
However, I did enjoy flying the Zlin. Climb performance is probably similar to the 'dog (i.e slow), it handles very well, nice and sharp, and rolls faster probably due to more stuby wings. Spinning is a doddle, visibility is great and overall a lot of fun. Be more than happy to strap one on again.
