YMMV, but I can tell you that I got a 14 hour shave with the BronTi with no discomfort or irritation during or after the shave. I can't say that with either the La Faulx or the Amakuni. The longest shave results with either is 11-12 hours and alum burn with both. I can't imagine a cheap SE/AC razor can perform that well.Don’t think they are worth it, I bet they do not Shave any better than many cheaper AC/SE.I have recently had extremely good Shaves with very early AC/SE Razors.
