Effort vs. Production

What's better, someone who tries hard but can't get it done or someone else who can get it done but doesn't try hard? We all know people have natural talents at certain things which they can pick up while the rest needs to put in a little more time at it. When we are kids all that matters is the effort we put in at whatever we did, but as time goes along, the end product becomes more and more important. In the business world, I am sure the production is valued over effort. There are probably thousands of examples of people who give a hundred percent, but still comes just short while the person standing next to him is a prodigy at it. I often wonder to myself which of these two people would I rather be. I link it to intention and final result. Intentions can mean well, but I think I would be more of a realist and stick to what really happens. I know there is a balance between the two, though, as picking extremes is almost never a good idea. Still, I'm curious to see what other people think of this question and which person they would rather be; one who tries but never succeeds, or one who succeeds but never tries.
