My experience has been that contemporary vinyl is much more often warped or dished than original vinyl from the 60s/70s/80s, even 90s. It must be something to do with the pressing weight.
However, I have found contemporary vinyl to be very low on surface noise as a general rule.
I generally only buy new vinyl for the pristine sleeves that lend themselves to being displayed.
