Buying laptop has always been a compromise for me between performance, weight, price, screen, battery life and warranty.

so depends on your needs, the answer might be different. I would grade as such.

lots of travel -> weight(below 2kg), battery life(> 3 hrs), warranty (international?)
some travel -> screen, price, warranty
desktop replacement -> screen, performance(hdd), price
gaming -> performance(cpu+gpu), screen

my 2 cents.
