Main Cabin Extra vs. Preferred Exit Row
I've waded through several of the aircraft specific MCE threads and this question is generally not addressed. On 738s, S80s and 752s, my legs tell me the MCE seats definitely have less pitch than the exit rows. It's better than regular coach for sure, but you don't get the stretch out room that say 21A on an S80 gives you. However you're not stuck back in row 21 when it's time to disembark the aircraft so I've been selecting MCE for the past few months.
