I switched for a lot of reasons. I really loved racing the H20 and resisted changing. I also ran a chute on my H20 in some distance races which was fun. Since the H20 was not designed with a spinnaker in mind from the start it suffers from some helm issues under spinnaker.
I switched because I do like sailing with a spinnaker better. Also I saw the class moving to the F18 class Nationwide. I saw the Tiger as giving me lots of alternatives for racing around the country.
And contrary to what some others think in my opinion an H20 can not compete fairly against an I20 in a heads up race. An I20 is simply faster upwind by a good margin. An I20 has a 32 foot mast compared to a 30' 6" mast. It simply has a more powerful engine. I'm sure an I20 is also faster downwind but I don't have any personal experience to base that on.
