I am biased toward the milsurps because of them being a tangible piece of history, they are heavy duty and well made (at least the ones I have). I have shot only one modern econo gun and it was a POS. Rough as a cob, gritty trigger worse than any Mosin Nagant I have ever owned. The plastic stock felt cheap like a Bic pen. This is a single example so not statistically valid of course. Modern metal heat treatment is likely better.
The blood runs free, the rain turns red, give me the wine, you keep the bread.
