Trek 7.5 v Marin Terra Linda? Looking for woman's spec bike.

Rainbowcadenza

Would really appreciate some help on deciding between these two bikes. Am 5' 1" and very slight, so need women specific geommetry ideally. These are both within my budget. I have looked at the specs but am not sufficiently knowledgable to make an informed decision as to whether one is better than the other. This is a big outlay for me, but wanted to buy something decent. I am waiting for the bikes to be delivered to the store so that I can try them out, but would be incredibly grateful for any opinions/ advice. Will be using for commuting and cycling in my free time so wanted something fairly versatile. many thanks!
