Voted for Doris. I love her voice, an interesting combination of all sorts of emotions and subtle conflicting under-lying emotions.
Doris Day is older, or at least earlier, than the other two. My father used to play sometimes with Doris Day, before I was born. Every so often somebody tells me there are recordings that he's in, but I've never found any that I'm sure of (they don't usually introduce the pianist in the band - could be anybody). Evidently she was quite a character before she became the "Doris Day" sweet all-american girl she later became.
I remember Patsy and Patti from when i was little, 50's/60's. My parents' music, which means I was busy listening to MY music, and didn't pay any attention to the old folks's stuff. Pity.
