1 is the best
Also, dark red would be nice

#1 immediately caught my eye as it seems to be a compliment to the Classic Lathering Bowl. I was originally concerned about the opening being more narrow than the base and might result in clanking when loading the brush, but I'm willing to risk it.
#3 reminds me of the Seaworthy Lathering Bowl (my personal favorite) with the exterior ridge which may provide a more secure grip. I could easily move this one into first place.
#4 another winner since the tapered design might provide an improved grip.
#2 because one of them had to be in fourth place.
Scott, thank you for the opportunity to weigh-in on the prototypes. Be well and stay safe...
