I'd be very interest in option 3 depending on the maker(s) and specs. Option 2 would be interesting especially in Aogami from Togashi or Y. Tanaka and a revered sharpener but I don't think their existing dealer network will be friendly to this option. Option 4 is also fine, price and specs dependent. Option 1 I have issues with not only because I probably can't afford it but because it turns a tool into something dangerously close to an article of conspicuous consumption without actually improving functionality (and sometimes making it worse). If you feel the need to flex there are many other options.
My personal biases remain in place: (assuming a gyuto) 220 - 230mm lengths, wa handle, significant distal taper, heel height not to exceed 54mm, very thin tip, thin behind the edge,... also not in the really simple steels. MagnaCut, Z-Wear/CruWear, ApexUltra, A2, 52100, CruForge V, AEB-L, 14C28N are all vastly preferable IMO to the just C + Mn alloys. The 1.2519, Aogami 1 & 2, V Toku2 class wouldn't be my among my very top choices but I'd definitely prefer them to the Shirogami/1095 class.
Edit: 26C3 or 135Cr3 also preferable to the just C + Mn steels but again, not among my top choices.
