Help choosing Round Brilliant diamond needed

[Kal111]

Hi guys,

I have whittled it down to three diamonds. Please advise:
First I really like: https://www.bluenile.com/uk/diamond-details/LD14781846

Second one below- polish is very good would that affect the performance negatively?

Third one: just out of curiousity would you recommend strong fluor and faint brow? It's a lovely cut diamond with lover pricetag than the above two.

Any comments and advice are much appreciated
