WASR-10 without question. *Flame suit on*
I appreciate the history of the Garand, recognize that the quality, crafstmanship and overall condition of the gun will likely be better. However, this comes at a cost.
If it's a collection piece you don't plan to shoot, the Garand is the obvious choice. If you want a functional, rough and tumble carbine with 30+ rounds of rock and roll, the WASR is the better choice.
I have shot both, own a WASR, and chose to spend the $1K that could have bought a Garand on a DSArms FAL. You can get a Garand from CMP for between $445 and $595, plus like 20 bucks shipping, no sales tax, no dealer transfer required.
My knocks against the Garand:
*No high cap magazines or drums readily available
*It would be very difficult to "bump-fire" a Garand
*30-06 ammo is relatively expensive compared to 7.62x39 you can get 960 rounds of brass cased non corrosive reloadable surplus for 419.75 delivered via cmp, Its actually $75+$8.95 shipping per 192, so you don't even have to buy a case to get that price per round, 7.62x39 is only cheaper if it is non reloadable steel cased
*Larger, heavier and more cumbersome to carry in a self-defense
*Value of a Garand won't increase appreciably if there is another Assault Weapons Ban - WASR-10 would be front-and-center on a ban list and therefore be more "valuable"
with CMP you really are buying a rifle worth 1k for 600 bucks and the value increases steadily every year regardless of legislation
Did I mention the Garand won't accept hi-cap mags?
As previous posters have correctly stated you're really asking about apples and oranges. Garands are great guns and well deserve their place of honor amongst collectors - but I would still go for the WASR.
