Please help me chose an oval diamond!

I’m looking to upgrade my current engagement ring to a 3 ct lab grown diamond with yellow gold setting and a hidden halo. Was sent these three diamond options and am wondering if anyone could help me find flaws or evaluate if those are good ones?

I see a bowtie in all of them but also know that’s the nature of an oval stone, just want to have it less prominent.

Anything else I should look for?
