isn't this just genetics. Like why some cultivars have ACC FCC or whatever to represent they are slightly better than plant 2?
Humidity to some extend can play a role in the ruffled look I think. To me plant 1 looks in better shape with plant 2 having lost older leaves, possibly humidity issues but I'm guessing it's genetics mostly.
That is why it is best to have a few to always be able to pick the best one? Kim mentions this every time he shows a flower.
