I agree. I have had zero problems with waterproof panniers. Wet stuff either stays out or is sealed in ziploc or other waterproof bags to isolate them from dry stuff. No matter the type of pannier things that are packed away don't dry out.
The bigger difference is whether you prefer to organize things in one big compartment or in multiple pockets. Personally I find one big compartment more efficient. I organize things that need organizing with colored UL stuff sacks. That allows for some compression and I find it easy enough to find things.
