I have ridden multiple expensive wheels with different depths in the past 2 years (enve, roval, mavic, willier, pancho, etc) from 32mm to 65mm and between those sizes i personally felt not that much of a difference from depth alone (in terms of crosswinds) but depending on the manufacturerer the wheels behaved very different for me. for me personally the rovals where the best wheels because they where very stable in crosswinds and on descents. alpinist and rapide (i tried both extensivly) where very good for handling.
i have 69kg and ride 30mm tires with a bit less than 4 bars. I sold off all wheels but the 50-60mm i liked that depth best.
