Either is an exceptional razor for anyone. My Revisor 6-0049 was new, and truly "shave ready" IMHO. My Aust, I bought from an acquaintance who only had it 3 months. I honed it after receiving it (2nd hone job ever preformed (1k - 12k) and it shaved as well as the Revisor.
So, either I suck at honing, or it was good enough to feel as a professional job.
