I have had 0 problems with my Dell. On the other hand my Asus overheated within 2 years. My brother's MSI had similar problems. Honestly not sure which one is actually the best, maybe just certain makes?
@ OP, I bought a Dell Inspiron 7577 years ago, I think it is at least worth checking out that line of computers.
I've had too much experience with Dell and their propiitary garbage and even their Laptops literally physically fall apart. Alienware is esp bad in every way. Dell purposfully uses the cheapest parts and parts meant to fail. Complete junk.
