auto vs. 4 spd which would you choose?

i have a 71 halfton 4x4. currently it has a 4 speed. i also have a 71 4x4 auto (350) chassis with the complete drive train, less the engine. im about 80% (maybe, i think) sure that i am going to sell this truck. ive had it for so long its going to be difficult to make that decision. anyway, if i do decide to sell it which drivetrain will make it easiest to sell...stick or auto?...i would appreciate all your opinions, thanks.
