That's a mere 2 cm difference in stack and a 1 cm difference in reach.
TLDR summary: that small difference isn't going to matter. Get the one you like.
Unless you know for a fact that one of the bikes is the exact fit you want (and you can't know that until you've actually ridden the bike a good bit...), you're probably going to have to adjust the fit in the future anyway. And that difference in stack and reach is well within the range that's easily addressed by changing stem length and/or angle.
Stack height pretty much only really matters if it's too high to allow you to get as low as you want. Since you don't want to get low, it doesn't really matter for you.
Reach is also affected by the saddle position, and that's affected by the seat tube angle. Of those two bikes, the top one appears to have a slightly steeper seat tube, placing the saddle further forward. On that bike, you may find you want to have the saddle further back on the seatpost, or on the bottom bike you might want the saddle further forward.
But again, the differences are slight - a cm or two at most, and well within the range of what you can address by moving the saddle.
Be aware that saddles that seem great on a short ride can wind up feeling like you're riding a fence post, a spike, or a bowling ball on a longer ride. Pay attention to that, and be aware you might have to swap saddles on whatever bike you chose.
