I actually just asked a question about an FAL I got from a friend of mine a week or so ago. It's a very cool rifle and it's a monster but it's expensive to shoot!! 10 rounds (20 in your case) of semi automatic .308 at 50-75 cents a round is murder on your wallet. The VZ would be much cheaper to shoot and you'll probably have more fun with it because you'll shoot it more. The VZ is probably a better choice but I don't like AKs and I got the FAL for $350 so yea... In your other question I said that I didn't have any experience with the VZ58 and that hasn't changed, sorry I can't review that one for ya.

I would prefer the FAL, due to it using a more powerful cartridge that would make it more appropriate for hunting. Yes, it's more expensive to shoot, but I have a .22LR I can use for plinking. All the guns I want are on my list because they're useful to me. That's just me, though.

Ultimately, it's a matter of what YOU want. We don't know what you like in a gun, really. About all I can divine from this question is that you seem to have an attraction to military-styled firearms.

If you intend to do any big game hunting, the FAL might be a better choice, but a 7.62x39mm firearm is a fine 100-yard choice for deer, so long as it turns out to be accurate.

If you'll notice, though, the vz. 58 is backordered as of the middle of December of this year. It might be quicker to get the FAL, too. I guess it all boils down to what you want the gun to do.
