I really enjoyed the thread “Judging pitcher performance” so I thought I’d try to see what folks thought about judging hitters. But notice that this time I was careful to try to limit the discussion to amateur baseball. 
So here’s the question. Realizing that there are a million ways to judge ball players, what do you think is the best single metric to judge hitter performance? For many years it was BA, but that has definitely changed. Personally I like OBP or RC but realize there can be many other valid ways to do it.
A metric I like a lot but isn’t generally a popular one is “Bases per Out”, and another is “Reached Base Average”. I also like to see hitter contact percentages, and how productive they are by using Clint Hurdle’s productivity guidelines. Something else I look at a lot is how hitters move runners.
There’s just so many metrics it’s impossible to pick out just one as being the on best depicting how good a hitter is, but everyone has that one metric they believe does it.
