Leica V-Lux 4 vs FZ200: Any differences bud the adobe software?

I think the models have been in use long enough to at least do a survey of durability and reliability.

That is:

1. % of users who are still using {model} after {x} years, and

2. % of users who has to get their machines to repair, pre and post warranty.

I propose to use % because I imagine there must be far more panny models than Leica models.
