My F95T in Vanax 37 has become my most favored knife and steel. To me, it sharpens like a premium quality carbon steel. I carry it 5 out of 7 days a week and it really does have outstanding edge holding capability. I sold my Shiro in m390. I had an opportunity to pick up something else I've really been wanting and decided one of the Shiro's had to go. The Shiro in m390 was also an F95, and also in a really desirable handle (CF inserts). It came down to the steel I found I preferred.
So, what I'm saying is that all other things being equal (in Shiro's specifically), I'd personally pick the V37. It's worth it. There are plenty of knives out there in m390, Elmax, s90V,... but I do not know of any other folder in V37.
