I post this not to renew debate on current Nikons vs. Canons (or Sonys), but for those who visit this forum because they haven't yet decided on a camera system or are thinking of switching.
I find Jan Wegener's videos entirely balanced, and he "shows his work," even though he benefits from clicks like almost everyone on YouTube.
Bottom line: Nikon wins going away in certain categories, as does Canon.
Go to the last couple of minutes for his summary if that's all you're interested in.
