i think its ok.
i like the 753's. not for their lack of FC seats or their enromous legnth but for the fact that they're nice and new and i think the seats are very comfortable. when you recline, the bottom cushion slides forward, giving you more of a recline, i think. coach isnt the best but i would bet im bulkhead or exit row 99% of the time on all CO flights. i have the luxury of booking early.
FC seat pitch is the same as 737. and i like the exclusivity of the small FC cabin even though im not always in it. i still dont get the 12 FC seat thing though. stupid in my opinion.
