I would prefer the second position (and the second cockpit layout). Providing you have a decent bimini, the fact that the wheel is more open/exposed shouldn't be a problem. General all-around visibility will be better from the second one and sail trim will be easier too, I guess. But whatever floats your boat
To me, the first photo looks like the layout of a motor-sailer, whereas the second looks like a yacht. Not that there is anything wrong with motor-sailers per se (horses for courses and all that), but frankly (letting my prejudices show), if one intends to spend most of one's time motoring, one might consider purchasing a motor boat!
