...the tendency seems currently toward less overtly crinkly diapers.
I like crinkly diapers too! I would guess that the cause of the trend is wider customer appeal. Not everyone wants a loud diaper. As much as I love having a crinkly diaper, there are still times I want it to be more discreet.
To OP's question, I personally haven't experienced too much variation based on the brands that I've used.
