I'm a diehard Row 1 devotee, but recently I was in 3D on a 739. 2D reclined his seat all the way, which doesn't bother me, but there was barely enough room for me to get out of my seat without jostling his seat which is something I pride myself on never doing. And I am slender and able to easily maneuver in/out of seat rows without grabbing anything for support or balance. Not exactly a "first class" experience.
