talking more affordable knives and what steels i like best....
i only carry a knife daily more as a standard cutting tool, than a self defense weapon. in that regard h1 steel is my favorite. doesn't rust at all, ever. which is a huge plus in florida summers and holds a pretty good edge. no not the best edge holding ever, but good enough for my uses. also easy to keep sharp.
vg-10 is my next favorite stainless, although i've had good luck with most stainless except when bead blast finished and the 13v26 and 12c27 sandvik steels. which hold a good edge, but rust extreme, at least for me.
for bushcraft/survival i really like carbon steels, 1095, 1075. easy to keep very sharp and while they rust easily, they can take a supreme beating and keep going.
in the end though i own knives in d2, a2, various carbons, 440a, 440b, 440c, the various chinese steels like 8cr13mov, 420hc, aus8, s90v, s60v, s30v, 154cm, sandvik steels, h1, vg-10, and various others...and i find they all work pretty well, for most tasks. i like the various steels and slightly different advantages and disadvantages they bring, but i'll be the first to admit....it's easy to overthink the steel. depending on the task they all work if done right and properly made and maintained.
