In bike parts there is a such thing as going with too high a viscosity, just as bad as going too low. A lot of the marine greases will be on the thicker side, thats why I say toward the lighter side. The cheaper white lithium greases can be too thin for wheel bearings. I have also(people will shoot me for saying this) found Phil wood to be too thin for hubs. It works for other bearins but not hubs. As a rule I don't care for Pennzoil products(I know im a PA person). Amzoil makes a very good product, but again watch the viscosity, since a lot of their higher end greases are made for super high temp work. The highest a bike needs is 450(heavy use disc brake) so a normal automotive disc grade will work. Through my experience, Valvoline makes a good cost-effective and reliable product. #614 works in every application I have tried it in, and it will not age from sitting(One can in the garage is 30 yrs old and still looks the same).
Bike greases are potenitally different, but they are mainly hype. To pay 5 times as much for less grease is absurdity in my opinion.
