70-200 L f/2.8 IS II + extender
or
70-300 L?

the 70-300 L has been released for a while but so far dcfever only has got 4 user reviews. i have a feeling this lens isnt as good (image quality) as 70-200 f/2.8 IS II.

Great price difference for these 2 options. Known that 70-300L cannot attach to extender.
