Plus on the 787 you will be “top dog” whereas the 77w has a first class cabin

Beyond that I would personally choose JL because the apex suite is IMO the best business class seat out there (I’m tall with big feet). Open and airy vs. enclosed and claustrophobic like most these days. NH has their old staggered biz seats which, while serviceable, don’t compare to the apex.
