I have 5000 hours and am learning every day. Am I a better pilot than I was at 4000? Yeah.

Some folks 'get it' sooner than others and that's great. But in general more hours means you've seen more and know what to do in a given situation and what your personal limits are. And your airplane's limits and how it behaves in certain circumstances.

More hours doesn't mean better pilot in the 'stick and rudder' sense, but it usually means better judgement simply because the high time pilot will have seen more things than the low time pilot.
