Looks like Kowa > Oberwerk or APM > Vixen
The Kowa have superior transmission .. the Oberwerk are big heavy and have marginally better optics (triplet objectives and bigger prisms) than the APM ones (doublets) and both better than the Vixen cans.
The premium Japanese optics are still supreme over Chinese stuff but at a price.
