Fairly different customer needs/prioritizations. The M2 Air appeals to customers who place a high value on smaller size and weight. The 14" MacBook Pro appeals to customers who need processing power and greater memory/storage capacity and are willing to trade off lower size/weight to achieve those performance goals (or those who truly want a larger screen). The 16" MacBook Pro appeals to those customers who need the power and have a need or desire for a larger screen size when mobile. The 14" MBP is sort of in a sweet spot between the Air and the 16" MBP, but its not the best fit for everyones needs/wants...
I would still like to know if the M2 is already capable of beating a M1 Pro since it’s a next generation
