That is what it comes down to is preference....for a vast majority of criteria.
There is excellent performance to be had from many steels, top quality aesthetics from many makers.
Some knives are "better" with stainless steel and hollow grinds; chute knives, subhilts, utility knives in marine environments....
Some knives are "better" with flat grinds and carbon steel, swords, though not knives, are almost exclusively in this category, big bowies with distal taper, hunters, where the emphasis is on thin, easily sharpened, razor edged cutters....
Collectors, just like makers, should have an idea of what they like best, and go for the brass ring. I was slinging the crap

, and although I don't care for Mr. Mandt's Moran, I CAN appreciate that HE cares for it, it may be the cornerstone of his collection, and that passion and commitment is to be respected.
The same can be said of the makers, regardless of production methodology. The skill, passion and commitment, specifically to be full-time, and to have faith and dependance on one's skills to put food on the table, ESPECIALLY in this day and age is to be respected.
