No question about it, some low-timers are light years ahead of high-timers. It isn't all about flight time in the log book any more since manipulating and monitoring autopilots is the same for one hour or ten hours.
It's not a matter of practice makes perfect, it's 'perfect' practice makes perfect.
So definitely, quality of flight hours play a far more significant 'experience' than total time alone.
Having said that, most of the time, better airmanship will favour the more experienced because nothing can ever replace good experience that only time can deliver.
The insurance companies recognise this and therefore it becomes a premium expense for an airline which pushes for lower times for commanders. (The very same reason why car licence holders of less than two years in Bahrain pay more than double the excess if they have a prang and/or pay much higher insurance premiums).
If GF decides to pursue this, they will have to be prepared for a massive spike in their insurance costs, and, ensure a much more rigorous training and monitoring regime than the current for low-time captains, and, pray nothing untoward happens.
