Generally it is next to impossible to point out the best brand among the two you have given. It is all about the specific models of the laptops from each vendor, or about a particular laptop that has some manufacturing defects.
I would suggest you to pick one laptop model from each of the vendors of your choice and then compare the laptops and check the end-user reviews for each model. This way you can get a better idea as which laptop should you pick.
After picking the laptops for comparison, if you are still unable to decide which model you should go for, we are always here to help you.
