Personally, I don't like the ergonomics of the cz. Have sbr scorpion at the shop, factory sbr kusa, and kusa with brace. I'd take the ak all day. The brace version is nice even. Not as cool looking as a triangle folder but just as functional. People say to get the psa because of the scorpion mags. Imo it's a slight against them. Kusa takes factory Russian mags, which most ak enthusiasts would want at least one or two of. The only reason imo to get the psa is because it's cheaper. The kusa is a pretty good clone of the real deal.
