Regarding Pitts vs. Christen, many Pitts's are homebuilt whereas the Christen is always factory built. As a result, the Christen will appeal more to the "I want it now" type of pilot with money who buys more airplane than he really should?

Regarding Stardusters (Starduster One, 105mph cruise for mine at least), I can attest to its stoutness after my forced landing and subsequent cartwheel. The Stardusters are less intended for hardcore aerobatics than the Pitts or Christen, which may speak to the kind of accidents.
