At the beginning/intermediate levels, most matches are won by whoever is more consistent. Great strengths haven’t yet developed, and so while players do have strengths, the matches are mostly won by whoever makes the least mistakes.
As you advance, this changes. At the intermediate/advanced level, matches are mostly won by whoever gets his strength into play. The looper wins if he gets his loop into play. The hitter wins if he gets his hitting into play. Even the steady player – and steadiness can be a strength at all levels – wins if he’s able to get into rallies where his steadiness prevails. And so on.
