Of the scopes you list I would rank them in the following order in terms of quality:

Nikon Team Primos - these are last-years Nikon Monarchs, an excellent scope

Bushnell 3200 Elite - Skip the firefly reticle though. I have a 4X12 3200 on my coyote gun and love it. The rainguard feature really works.

Nikon Omega - I personally don't like the big circles. Look at a Burris Fullfield II with a Ballistic reticle. Very good scope for the money and they have been making these scope reticles a long time.

Nikon Prostaff - nota bad scope for 100 bucks actually.
