Anyone using that 55-300mm VR Nikkor? How's the results?

I read some of the user-reviews of the brand new 55-300 VR

and they seem really contended, satisfied - though it lacks that manual focusing override like its predecessor, 70-300 VR FX lens

So what do you say, if we have a DX camera, and don't want to upgrade towards a costly lens, may we dump the 70-300mm and get along with our new 55-300mm VR?
what about the manual focus override? Does this thing really matters?
M mode focusing is not enough precise and crisp at 300mm end, in 55-300mm?

Examples of picture by various photographers using that lens. Take a look and decide for yourself.
