Noobie question - lens quality and f-stiops

Guys,

I feel a bit embarrassed having been exposed to proper photography with Nikon for the last two years, yet I still have a simple noobie question. Any answer is appreciated.

Generally speaking lens quality usually equals two things on a forum: large F-stop (F4 or F2.8) or primes. I also see that constant aperture helps when choosing lenses.

My question is: while F2.8 helps in low-light, if I have 2 lenses (e.g. 50mm F1.8 at F 5,6 and 16-85mm at F5,6 would I be able to tell the difference of quality, regardless of lens, or the 50mm at same F-stop will produce similar quality image (e.g. same ISO setting needed) - the difference maybe only arising from additional sharpness from prime (but no other advantage)?

Is this correct?
