Realize that a smaller frame size of the same model will also have a lower stack height. So that closer bar will also be lower. And new bikes come with the bars as high as they can go. Without making them fugly with other added stuff. And used bikes might have the bars slammed and the steerer tube cut. So also requiring more stuff to get the bars higher.

Ride the bikes for as long as you can and then make a decision which you like. If you buy one and then find out you don't like it, then maybe you should have gotten the other. And will better know for your next bike purchase.

Being stretched out on a bike isn't necessarily a bad thing. You'll be more aero than with the bars closer to you and your arms straight. So that'll save you watts. Or you can save watts by having the bars close with a lot of bend in your elbows. Either will also help keep you from getting numb wrist and hands. Assuming you also can hold the hoods and bar correctly.
