There is nothing called best Laptop Brand as you put it.
you should say which is best Brand for Specific usage.
- Best for Business. that is portability and battery life and endurance.
- Best for Engineers and workstation users.
- Best for Gaming.
very Few Companies make Workstations Laptops , and very few make good business ones ... etc
IMO ,
1- Best for Business , Lenovo Think Pads , Apple
2- Best for Workstation , Dell then HP then Lenovo
3- Best for Gaming , MSI then Asus then Dell
you cant mix those in one basket.
and if you want Rugged Laptop , Only Panasonic Tough books.
