I think active pickups give more punch and an extended frequency range to a bass. Some modern active basses sound a bit too trebly for my tastes, but the Yamaha has a nice balance.
The action is pretty good. You need a little bit of air between the strings and the board to get the "thunk", but it certainly isn't a difficult bass to play. It's got height-adjustable saddles and a truss rod, so the action can be adjusted to taste anyway.
It's also a good instrument for a guitarist - not too huge, as some basses can be, and everything falls nicely to hand. Mind you, I mostly play the guitar fingerstyle, so I think my transition to bass was a bit easier, but once you get the hand of the "walking fingers" (alternating forefinger and middle finger) you're away.
