Perhaps hours are not the final criteria of 'best'.
Certainly spray plane pilots run up the ours, but vastly more importantly they have a high percentage of close to obstacle maneuvering during those hours - as opposed to a trans ocean cargo/passenger pilot watching the air flow over the wings as the autopilot follows the routing and as it shoots the CAT III, zero, zero landing. (not picking on the ATP pro's)
Or perhaps an airline feeder pilot in a clapped out 411 who loads the bags, counts the heads, then flies the plane on a series of 20 to 40 minute legs for 10 to 12 hours. Then does it all over the next day.
Or the commercial pilot hopping passengers on 12 minute flights at county fairs, 12 hours a day.
Or the CFI at a big flight school who works a couple of weeks at a stretch grinding out the circuits and bangs with primary students before he gets a day off.
Or the powerline pilot dropping workers onto 350,000 volt lines from the chopper.
Lots of flying is done without running up 5 figure logbooks, that takes lots of skill
BEST is relative.
I don't have a lot of hours, but I have been banging around in planes for well over 50 years. Must count for something, eh.
