My first vote would be for Transhuman Space. 2300 AD just assumes things will be the same as they are now, doesn't that seem like its being dated? Now for sheer volumes of information I would say Traveller, given that I have quite a bit of it from Original Traveller, Marc Miller's Traveller, GURPS Traveller, and Megatraveller.
Of course you could just figure out how to game in Orion's Arm
(http://www.orionsarm.com) and get the best of both universes.
