hi Northern Sky
i am great fan of Mr Boeing,infact the 737-200 is still my favourite piece of flying hardware(no fear of anything remotely resembling software here,if you dont count the PDCS or the hand held GPS!)
But i am also an A320 driver.My airline owns 30 of these machines and has a further 8 on dry lease.They all have 3 IRS's and 2 FMGC's as standard equipment.i have not had occassion to compare the 737 NGs A/P with the 320s,but we are quite happy with ours Thankyou.Perhaps in future you will endeavour to get your facts right,before jumping into the fray!
Happy Landings
