I recommend going with the frame size which allows the use of a "normal" size stem. Normal is in quotes because, what's "normal?" I can't really define normal, but I know when it's not. Have you ever spent time riding a road bike with a 50mm stem? How about a 140mm stem? The point is, at either end of the spectrum, handling starts to get a bit weird. There are benefits to go bigger frame, and benefits to go smaller frame. There are also drawbacks either way. If your frame size choice puts you at either extreme for a stem, then you're probably not gonna be happy in the long run. Personally, I'm ok with 90 - 110 stems on drop bar bikes. I feel comfortable going a bit shorter with flat bar setups. It's all a matter of personal choice but I wouldn't put myself at one extreme or the other.
