They said the H is a "true H" per the vendor with "no visible tint"
Congratulations! Reading through, I think the 1.70 is the more obvious choice based on what you've said about your SO.
In terms of cut, there is very little between them and I don't think anyone can pick one over the other in terms of superiority based on numbers alone. The only way to differentiate them is to see them in person. Arguably the slightly smaller table on the 1.70 should help give it a bit more fire.
All the best
