A few years ago, I'd have probably said the opposite. But I prefer Bess/Bessie over
Elsie. I'm not sure when or why that happened. But I don't think of cows. I think of "Good
Queen Bess",
Queen Elizabeth I, which gives it more character than
Elsie in my opinion.
Elsie is darling, too, though. I just like
Bessie more.
