The F1 has way too many good reviews and supporters to ignore.
The convex grind is where it is at for me (on other knives).
I don't own a Falkniven, but would not hesitate to do so.
The laminated steel is great stuff as well.
I love Resiprine C, it is my favorite handle material. Scrapyard make a great product, and the elamax releases are very exciting. They have one of the best warranties and customer service in the industry, and the resale value is great. But, the current releases may be a bit thin for what you are thinking. One of the current elemax releases is .08 if I remmember correctly? I would not hesitate to make fuzz sticks, but I would not try batoning with it. (if it breaks they will replace it, but it is not a chopper or batonning knife).
I also feel that the choil's on that size knife are not necessary (some love them).
The choils on the elemax knives do seem like a great spot for a fire striker though.
I am a Busse/Swamprat/Scrapyard fan for sure. But won't force them on anyone. Some of their offerings are too thick for "bushcraft" uses. But I have a handful that are great (thinner convex grinds). Infi is great for stain resistance, but out of that budget, and you would have to jump to get a good deal on aftermarket.
Get the F1 and use it it in good health. I bet you will love it (as most do).
As to your original question, I have a few knives in Aus8 and have been fine with the steel. It resists stains great (rafting, and swimming with mine have yielded no rust). It sharpens very easy, and if given a quality heat treat is a pretty tough steel. Not the best edge retention (the F1 will have better edge retention for most chores). As others have said, the $150 price range will give you more options and better steel than the Aus8.
