How about a VG-10 Endura? As a lockback, it'd be less likely to disengage than a liner (probably not relevant, but one of my irrational fears). Also, it'd cost less.
OTOH, S30V is easier to sharpen and the Mili is bigger so it could handle bigger foodstuffs.
Wish I had a better answer. Would've recommend the S30V Native Lightweight, but I have a post about something odd with that.
