My choice for best is Redline. Here's why (from their site):
Check them out at redlineoil.com
Red Line Gear Oils contain polyol ester basestocks to provide excellent lubrication even under extreme conditions of high-loading and high- temperatures--their natural lubricity provide excellent slipperiness which reduces the sliding friction in hypoid gears to reduce wear and temperatures. The synthetic basestocks have a natural multigrade property, so large amounts of unstable thickeners are not required to manufacture our gear oils, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use.

Last time I used, umm, err, Amsoil. 
75W140, to be specific. I did the very non-scientific smell and fingertip tests, and it smelled much better and felt more slippery than either the Pennzoil and Sta-Lube gear oil I was using before. Either the store didn't have any other synthetic gear oil, or they were much more expensive than the Amsoil since I don't normally buy products from them.

I figure it's in there for 100,000 miles, so why not get the best. Redline is $8 a quart (myoilshop.com $7) and is supposed to be among the very best. Have it in my motorhome (3.8 qt capacity) since about 3000 miles ago. Of course, regular rear end lube probably is fine too. My (not mine anymore) '84 F150 is over 200,000 miles on the original rear end and lube and still running. But I like overkill.
