That's a beautiful knife! The only issues I have are the following: (1) I wish it were the smaller sub-3" version (just a personal preference); and (2) more importantly, the fact that SK Knives will not honor returns for blade centering ("blade centering not considered a defect") is an issue for me. This is only because I've handled many a Buck Vantage in brick-and-mortar stores, and the quality (and blade centering) vary widely. I'd just be disappointed to be stuck with a badly miscentered version.
Regarding high-end steels, I'm not too motivated by that either (give me some 440C and I'm happy), but I must admit I do love how my M4 knives have been performing. This Mantra 2 (the best Mantra) was reground by Josh from Razor Edge Knives to make it quite thin behind the edge, and it just keeps cutting and cutting:
