William, I am not intending to revitalize the M vs W fight. I am fortunate enough to own both, and I didn't even realize there was a "fight". I am speaking only for myself, and only from my own experience.
Various types of stock design have come and gone from both manufacturers, however, it is generally true that M. prefers a large, in my opinion, overly large forearm, which negatively impacts handling.
Not all Winchesters are light and nimble, but the 94 certainly is.
Yes, aftermarket sights have long been available, and thankfully, marbles, williams, and other continue to produce them.
Thanks for writing about your experience, it was insightful.
