This lens is a modest upgrade to Nikon's original 300mm f/2.8 VR. It's 99% the same lens, so pretty much everything you've read about that lens also applies to this one.
What's different, then? Well, this one has a slightly improved VR system - Nikon claim 4 stops of shutter-speed improvement, versus 3 stops for the older model - and a somewhat confusing new "M/A" autofocus mode to complement the existing "A/M" mode. Nikon also make a big fanfare about he fact this this one has their Nano Crystal coating, but the old one did too (without the fanfare).
This lens works very well with Nikon Teleconverters and it will still deliver superb image quality. The 1.4x Teleconverter makes it a 420mm f/4 lens; the 1.7x Teleconverter makes it a 510mm f/5-ish lens; and the 2x Teleconverter makes it a 600mm f/5.6 lens. All of these combinations will retain autofocus and VR on all compatible cameras.
