Just a couple of thoughts.
Some,few,experienced cooks can tell the differences in smoke flavors,except bad-or negligible.
A slightly higher percentage can tell the difference in aromas.
As the cookday goes on,our olfactory glands become desensitized to the smoke and the percentage drops.
This is a reason that we may taste and smell smoke more the day after we smoke.
Oak is considered the "queen"of cooking woods.
Stickburners often use a blend of 30% flavor woods,and 70% oak to mellow out the flavors.
Stickburners,that don't control airflow,burn,etc are also more prone to oversmoke.
Restaurants that grill/bake over hardwoods use high levels of oak,as it gives a subtle smoke without ruining the meats and seasonings from a quick cook.
Comp cooks are so good,that tiny subtle differences,after all else is considered.
The correctness of cooking the meat,the tenderness,the way it bites,chews,swallows,the appearance,does it taste like the MEAT,does it have an off flavor,or aftertaste.
Did the cook try to hide a bad product with sauce and rub?.
Can the meat stand on its own?
Cooks, for the money ,often depend on hickory and pecan as their nutwoods,or strong flavors.
Apple and cherry dominate the fruitwoods.
A rare couple use some peach,or citrus woods.
On large volume woodburners,that burn down to charcoal,oak is used and then a flavor wood to get the accent.
Mesquite is usually a grilling wood for its high heat.
Some Texas stickburners may use sw Texas mesquite as their flavor wood in addition to oak.
Cookshacks burn a small amont of wood,very efficiently.
The company supplies the few most popular woods,in managable chunks,cleaned and correctly aged.
They are not in the wood business,but want their cookers to perform at their peak.
Most good cooks will tell you that although mixing rubs,and sauces,and blending woods is fun-if you like it and don't cook much,learning your cooker and how to cook the meats is more than 95% of what you put on someone's plate.
Most top comp teams buy someone else's rubs and sauces and tweak them for taste.
That way,they can focus on the 95% that they MUST have.
