Comparing
I see zero bowing on either. If you pull on the front button there should be about 2 inches of space (the gap between your shirt).
It's hard to compare that Havanna since it's linen/cotton and completely unstructured.
Comparing the Jort in the original post. The 48 seems more balanced and proportioned in total. The 50 gives you more boxy shoulder look.
Maybe others have different thoughts, but I would opt for a 48 and skip alterations.
