Agree, and I am guilty of thread drift too.
Back to the OP, in the summer if its nice I will wade in in shorts and flip flops. The rest of the time I wear these Ron Thompson Neo-Force Waders (Cleated 40/41, UK shoe size 6/7) | GO Outdoors
The reason why I prefer waders is I have a newish car and it is easy to jump out of these quickly to drive the boat and trailer up the slip after launching/recovery without getting saltwater in the car. Did it once in a rush in a drysuit with my wellies on and the wells were full of water when I sat down all the salt water in the wellies went all over the foot well....not good and stains
I suppose a drysuit is safer if you tend to launch in deep water in case you slip over. You will struggle to get up if your waders fill up. As I know the depth of my rib I am never more than knee height when launching/recovering.
Hope this is helpful
