Unfortunately when answering a question like this the answer is primarily based on personal preference.
I would definitely stay away from Razer, their products cheaply made and are overpriced
I woudl totally disagree with that statement as i have several “Razer” based pieces of equipment, Keyboard, Mouse and keypad, all of which are very well made and i have had no issue with them… although i would agree they are expensive. On the other hand i would also say that ASUS… is the definition of cheap, ACER… still cheap… ( isn’t Asus the cheaper version of Acer anyway ? ) both my personal option obviously.
I would suggest the following when looking, if your into gaming you will know why
GTX based graphics card… 1070, 1080, etc ( not going to be cheap )
Solid State Drive - large as possible… maybe consider a hybrid for storage
16 Gb RAM
Decent quality screen ( 17" ) this makes for a large laptop but you want quality and performance not small and light… i presume
That’s it really… the ONLY other thing that sets one manufacture apart form others is good support… when your spending good money on a gaming spec laptop… if it goes wrong you need support and a good warranty… Dell for example… on higher spec machines have great warranty support… ACER or ASUS… good luck basically ! can’t comment on Razer as my stuff hasn’t broken…
Hope that helps… at the end of the day all the components are from the same place, Intel etc… all the “goodies” otherwise known as bloatware… would get uninstalled anyway… so it comes down to the list above … and cool factor… don’t forget it needs to look cool…
