Well biggest thing is new MB air cant get i7 processor, it really depends on what you are doing with the laptop, I would suggest anyone you get, get 16 gb ram 100%, then if you want better processor get the i7 and not i5, i would get at least 256gb internal storage since 128 could get filled fast and buy an external harddrive which is alot cheaper vs getting more internal storage, say 1 tb external harddrive is like 50$ vs buying more through mac which is ridiculously expensive. Also alot of people complain about the keyboard, they just updated the keyboard on the new MBP so if your going mac, go to the store and talk to a sales person about what you want to use the computer for, bigger screen is also nicer but you gotta pay to play, 13in is nice but 16inch is nicer but also way more expensive lol. 13inch with an extra monitor is always nice, that being said if your running a website, shipping, logistics, builds, pictures, ect, better to get one more expensive that you like and fits your needs vs something cheaper
