Whatever the theoretical differences (in terms of assumptions about the distribution of the latent response variable, conditional on covariates; not the marginal distribution), in practice both will give you substantively the same results. (The coefficients will be different because they are normallized differently, but the size of effects in terms of substantively meaningful things like predicted probabilities will be indistinguishable.)I agree. The choice may just boil down to what the common practice is in your field. Seems to me like I see a lot of logit/ologit work in Sociology, and also in the occasional medical-related research that I read. In economics I see probit/oprobit being used some.
