As for companies, there are several you should avoid, Dell and Alienware, they do not uphold their warranty in many cases, BBB takes bribes and their tech support/RMA is basically mailmen, they force you to use only their drivers, have common battery reflated problems. Also few certain models of laptops from other companies, you just need to google the make model and see what Owners lounges are talking about.
Generally the Mid range laptops from HP are pretty sought after.
ASUS/MSI/SAGER are considered the gaming laptop manufacturers of choice, each one has some kind of advantage that's distinctive to that company.
For example, Sager is a German brand, they really don't mess around with Quality, as in its top notch.
Asus is pretty decent with cooling, prices, choice and general innovation.
MSI tends to be on the costly side, But you can expect all the bells and whistles to be included in their laptops
