JL by a mile for me. Not a fan of The Room. Hard as a rock and while obviously ultrawide, it's short and angled terribly with the hard product literally cocooning you so that if you're on the taller side it really sucks for your knees and shins. If travelling with a lap infant, the width is handy.

Even if you get swapped to a 77w (which has been happening this month as there is an aircraft issue) you then get the Apex suite which is a fantastic seat imo (again, opinions vary and for someone not-as-tall that doesn't have to wear clown shoes they might prefer The Room).

All that said, obviously this is a first world problem and you'll have a great flight either way!
