Thoughts and recommendations?? Can’t decide on the shape!

Hi everyone, I tried on rings today for the first time with my boyfriend, I think he’s proposing soon. I am torn between the oval shape and the radiant shape. The setting the diamond is in is not the actual setting it’s just something that holds the diamond so I can try it on. I am obsessed with the emerald bezel wedding band that I have on with these rings, but every one says it on matches with the radiant one 😭😭 thoughts and suggestions??
