I wouldn't go far out of my way for p.s. C over 763 C (i.e. take an extra connection), but, given equivalent schedules, I would strongly prefer the 752 over the 763. Part of it is that I dislike the 763's narrower seats. Part is that the 752's C cabin feels more open and airy than even a 777. The better meals, IFE, and 120VAC are just icing.
