The 'ability not hours' philosophy is even more stupid than the 'hours not ability' philosophy.
All other things being equal, such as ability, the higher hours pilot has a huge advantage over the lower hours guy. That does not presume though that the guys with higher hours is automatically better in any situation because that patently is not the case.
What is certain though is that the low hours guy with low ability, who presumes to be superior to his seniors, is a disaster waiting to happen. You will see (and definitely hear) him in every airline, though usually not for long.
