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.
