I run 4th Edition because...it is the current, supported edition, and I am not having to play catch-up on getting books.
Of course, since it is the supported edition, that also means that my FLGS can get it in. Additionally, while
the system has the complexity of previous editions, it is a simpler system to learn the basics of.
That was one of the main reasons I finally gave in and got 4th edition. I skipped 3rd entirely but realized that unless a game is D&D it runs the risk of being abandoned at some point where it becomes non-profitable.
Fortunately, Shadowrun has a very unique setting. The advantage is that it's hard to copy without being too obvious (D20 Modern tried and may have succeeded at being a worthy successor). Generally, if you have cyberpunk elements with magic... It's Shadowrun-esque. Throw in elves and dwarfs... it's a copy.
I decided to go with 4th edition to help support it. May go back and get a few older books from 1st thru 3rd to help flesh it out, though. My fave resource is Sprawl Sites (a book I borrowed from a friend's brother, oh, yeeeears ago...).
