I like a gun that looks nice.
Ignoring other things, that's fancy figured walnut and polished blue -- and yes, you can even make a top-notch varmint rifle that way.
However, walnut and blue don't look so good after being dragged through gravel. So there's sure a place for stainless/synthetic.
I hate rust, so stainless especially can appeal to me, but then again there's not much of it in my safe.
WRT technology, synthetic stocks can be the worst, not the best. Sure, some modern composite stocks are amazingly stiff, light, durable, ergonomic, textured for great grip, attractive, and really expensive. Most base model "synthetic" rifles, though, sit in something only a step above tupperware. Plastic molding can be cheap junk.
So don't think that synthetic necessarily gives you "the best technology". If you're not paying a lot for the rifle, it's probably just the cheapest thing the manufacturer could screw a barreled action into.
