In my experience, the Yugo 24/47 is more likely to be a shooter. The Yugos I have seen all had good bores, the few VZ-24s I have seen had pitted bores. My VZ-24 had a very pitted bore, but still shot well. Both of my 24-47's have very good bores, one has a new barrel.
For a shooter, go with the 24-47.
To build into a sporter, go with the vz-24.
For collecting, get both, thats why they call it collecting.
