You see aero benefits, but they depend on the width of the mounted tire, the amount of turbulence in the surrounding air, and most important the speed involved. IMO it's borderline meaningless to even think about aero at speeds below 20mph, and real benefits don't accrue until nearer 30mph in non-turbulant conditions.

So if you're a breakaway rider fighting not th get chased down, every bit helps. But if you're in the middle of the peloton, even at 30mph+, the aero differences won't be as meaningful.

Personally, I hate deep section rims because I ride in areas with gusty winds, and don't like the sail effect of deeper rims in crosswinds. So, if it were me (who rarely rides 30mph under power) I'd opt for the shallower profile, but this is your bike, so you'll have to toss your own quarter, and call it in the air.
