Having recently flown FCO-SCL-FCO and FCO-EZE-FCO I chose 3A (twice), 3L and 1L and these are my preferences in the main cabin and would try to get these again if flying AZ B772. Not been in the mini cabin though. Had the A332 on the FCO-GIG-FCO (3A on both flights) but prefered the B772 as seemed to be more width at the seats due to the wider airframe.
