I think plasticky just means it has so much treatment on top of the natural hide that reminds one of pleather/vinyl/faux leather to the point where in a blind grope test with a convincing faux version, you wouldn't be sure which is real or fake. On the far end of the spectrum is patent leather which can feel like enamel! On the other end of the spectrum is glove leather, delicate lambskin which feels like a newborn baby and cannot be replicated in a lab, to my discerning finger tips. Not so far down that end of the spectrum would be nappa with a silky feel (and even merinos feels convincingly natural).
This is all neither here nor there because that's just one quality of leather people have preferences about and some bags
need to be hard wearing and durable, water resistant... I just don't mind if my bags are delicate. I have so many to rotate within that I would love it if any of my bags got worn out, I would feel somewhat justified in my collection if it didn't just grow and grow!

I only spend as much on a bag as I'm willing to lose if I wear it out to my eyes over dozens of wearings and then sell it for a small fraction of what I paid. I'm cool with that. It has yet to happen but if it does I'm cool with that! I don't have perfectionist standards for a bags condition though, and I'm pretty good at rehabbing....
