Oval, round or Emerald?

I thought I was going to like Emerald but Oval looked nice when I was trying, but days passed and I kept thinking the round is nice and timeless. Help please?

Additional commentary: I overthink, my style is on the preppy side, I work in a lab so always have gloves on, I think my fingers are short. Character wise- I like to read(romance lol), go on picnics, travel and paint and lounge on my couch lol.
