ShadowRun 6e: A Possible Disappointment?

[Senkusha]

I was looking through DriveThruRPG at the various ShadowRun books, and didn't expect to see a SIXTH edition!  So, after poking around the site, I finally found the core book, and I read the very detailed reviews that were given, including one very long, exhaustive report on what to expect.

After reading that there are quite a few quirks with this newest version of my favorite Cyberpunk game, I think I'll just be sticking with my current favorite, fourth edition.  If you've had an opportunity to play sixth edition, what was your impression of it's mechanics?
