Depends if your height is in the legs or upper body. I’m the same height and fine on either, but short legs with high seat post are always more of an issue than length.
This is the non-silly response, as simply using height as a guide to bike size is , frankly, misguided.
There are other factors at play – i.e. Leg length, body length, arm length, preferred riding position, etc.
You really do need to try the two different sizes, if possible, to allow you to make an informed decision.
Speaking as a 6 foot tall man, with a 29 inch inside leg and gibbon arms, who falls smack in between sizes, for a lot of bike manufacturers, I feel your pain.
