There are laptops of this series with 60hz and 144hz screens, and of course different other specs. From what ive learned the 144hz screens are generally better, but are there differences ( as in are there worse and better 144hz screens that they use in these laptops, differences in SRGb for instance) or do they all use the same AUO B156HAN08.2 (AUO82ED) panel ? Ive chosen one with an I5-8300H, GTX 1050 TI and it has one of the above mentioned 144hz screens.
