B190 Enthusiasts

I am looking to purchase a b190 and have the option of a gen 3 or gen 4. Need to know which you prefer and why?

Any downfalls to having a gen 3 over gen 4? Or vice versa?

Take a look at this thread that lists differences between the years, and don't be afraid to peruse the two galleries (see links in the top right of every page) to see the differences on the Airstream part.
