Dell are worst among them. They honor warranties but most of the times they wreck perfectly working hardware and added new schemes to slow down laptops.Dell
MSI
ASUS
HP
I don't recommend HP because I have used a lot of HP products in the past and all of them are pos(piece of sh*t). My 3 years old HP printer which I don't use often is about to give up out of nowhere. HP stands for Horrible Product from my point of view. ASUS is not bad, but ASUS now is not the ASUS I know in the past that they are very good in quality department. MSI is a big no no in the past, but now they are very good in quality department and kinda much better than ASUS.
I have good experience with Lenovo's. Although they are cheap, their SW is good quality besides their phishing utility called Superfish or whatever!
