That's so true, we hackers operate in a world where many different answers can be correct. However we can generally gauge if a solution is better or worse.

I guess you would need to come up with some sort of metric to measure how much 'better' one solution is over another. A crude example which I've seen is the number of lines. To me that just shows how elegant the code is, but as you know it does not necessarily mean it will execute faster.
