I use Dell and i definitivily like them the most. But i don't think there is a best laptop. It all comes down to your budget and needs.
According to me, Toshiba has more features than others. I like Toshiba laptops with third generation laptops.
Depends on what you use it for... If you're just using it for office/business, then go with whatever is for sale within the specs you need and has a good warranty. Always check the warranty policies wherever you purchase. If you're using it for gaming/performance, I'd suggest looking into Sager laptops, or the ASUS gaming series.
