Given the two, I'm not overly fond of either. I chose Farming over Hunter, simply for the fact that I like free herbs for Herblore. Farming is also one of the few skills that is easy to multitask, as well as gain a profit. I plant all of my own seeds obtained through Slayer, and continue Slaying while they are maturing. I'm not sure on the exact amount of experience I've gained this way, but I'd be willing to bet herbs have been the main cause of my Farming level.
Hunter is just too boring. Standing in one spot for hours on end, just setting up traps. Sure, it can make you a bit of cash, but it takes too much effort. I would rather do a skill where I can multitask both in game, and out of game. Seems I can't watch anything online if I've got to pay attention to the traps
