I like them both and would keep them both. In my opinion it is not worth losing about a grand turning it over and getting a 42.
If you stay in good shape you will wear them both. If not some of us will gain weight others will lose weight so you are prepared for both
If you wear the jackets unzipped most of the time you shouldn't feel much of a difference. As others mention before the most important fact is how you feel yourself in the jackets. Some days you like a more comfort fit, other days you may want to wear a tighter jacket for the "badass feel.
Great jackets and fits! I hope mine still fit me that well in 20 years...
