As far as longevity, I've got about 15,000 on the SON wheel and 40,000 on the Shimano. Like you, I ride in all kinds of weather (except snow and ice), park in an outbuilding at home and covered bike rack at work. Though I repack the rear hubs annually, I haven't touched either dyno hub in the years since I got them.
