My friend has recently bought a 500mm F4 Sigma lens against my advice to get the Nikon lens.(Price was the problem). Has he lost in quality?

Let him enjoy and refrain from telling him "I told ya!" if he is truly your friend.
My personal experience is that you have to treat these babies with extreme care, otherwise .....
As for optical quality, he may not notice it much since he is not accustomed to Nikon's 500mm F4 sharpness and contrast.
In terms of focusing speed the difference is substantial as I recall.
But, the price difference is not small, the Sigma Telephoto 500mm f/4.5 EX APO HSM for Nikon AF-D is US$3,300; the Nikon AF-S Nikkor 500mm f/4D ED-IF AF lens is US$5,000; the AF-S II is even higher.
You don't save by going into manual; the 500mm f/4.0 P ED IF AIS MF goes for US$4,500.
I guess these lenses are to make money with them, hard to buy for the enthusiast amateur.
I hope your friend did not get the Sigma catadioptric 600mm f/8.0 Mirror (Reflex) MF lens, it is just US$379 but its quality is really poor. Mine is in the closet, as it cannot bring about but softness and no contrast. I may take it out one of these days to attempt its use with a much longer hood, just for the fun of it. After all, a not so hot lens is better than no lens at all.
Have a great time :-)
