Please help me choose between 2 round diamonds

Hi guys, it's decision time and I'm going to buy a loose diamond for my fiancè's engagement ring.
I've finally selected these two rocks, but undecided on which one looks better when mounted on a ring.
They are both SI1 checked and advertised as face up eye-clean. I've no pictures sorry

0.75ct, E SI1
HCA 2.0
AGA/NAJA Cut Class 2A

0.75ct, F SI1
HCA 0.9
AGA/NAJA Cut Class 1A
https://myapps.gia.edu/ReportCheckPortal/getReportData.do?&reportno=2136876782&weight=0.75

First one has a slightly larger diameter and E colour, second has a better cut.
Thank you in advance for your advice what the best choice would be
Cheers,

the F SI1 looks like a better choice.

F SI1 for me, too. Not advisable to buy without a picture or idealscope image, though.

Thank you for your imput, much appreciated
You're right, I've already asked for a clear picture or Idealscope image of it.
