Need help deciding between 2 round stines for an engagement ring.

Hello! I've been trying to read anything and everything on diamonds to find a reasonable and respectable center stone for my girlfriend of 10 years.

Of the two, which would you choose? I know the crown angles are a little steep, but these are the top two I came up with after an entire day of searching. Brightness and sparkle are of top importance. Thank you in advance!

I’m not an expert, but it would help if you could post photos in different lights, videos of each and an ASET image if available.

These are the only resources I have.
