I'd definitely consider the SGL 31 in 5.45x39, but for 7.62x39 I'm staying with the VZ 58.
But like the VZ2008 vs the CSA VZ 58 debate, I'm not sure that the Arsenal value over a Waffen Works necessarily justifies its cost...
Or heck, I think I saw J&G sales selling Saiga's doublestack coverted, tapco trigger, side rail, chrome barrel, etc, for ~$700 -- the same bones as the Arsenal, but minus Arsenal's added barrel threading, muzzle brake, hand guards, stock, and bayonet lug. Arsenal's have been running $1,000-1,200 or more, +$300 to +$500 over the converted Saiga.
Or for $600 you can get a Waffen Works 74 that basically just lacks the Arsenal furniture and custom muzzle break (fwiw, barrel is chrome lined and properly hardened but not hammer forged)...
My main reason for considering the AK 74 is that these days with good CCI 22LR ammo being so scarce and expensive, the AK 74 costs about the same to shoot, is a "real" full power rifle round, and is readily available... Considering the value proposition and the corrosive ammo, that further pushes me away from the platinum Arsenal option. Also, I think the 5.45x39 round and the AK 74 is a great platform for new shooters, provided they're properly trained how to and do clean their weapons after shooting...
