Which laptop brand is the best?

Now listen carefully, because it is really good advice: ITS All THE SAME!
The ilusion of choice is only in your head and brands are only good for social engineering.
Go at it from the other end - you WILL end up with a laptop anyway - so its only about how much you want to spend.
There's no such thing as "best brand". All of it is made in about 4 or 5 factories in asia.

Depends what you are looking to do:
-If you buy HP it NEEDS to be business side. Consumer laptops from HP are not that great but the business side is great.
-Lenovo is just plain hit or miss. You usually need to buy the higher end laptop for them to be decent. I personally wouldn't recommend it at all.
-apple, I love Apple. You would generally use it most for graphics design or music production. If you are doing neither of those, a PC might be best just because it is cheaper. I would personally buy a mac to use every day because there's less chance for virus (not 100% virus free like everyone says) and it is easier to use when you know how to use it.

HP is decent but needs alot of servicing, good if you want it for just basic work. Lenovo is real good if you r low on budget. But if you are willing to spend a little there's nothing better than apple. If you have a decent budget o would totally recommend apple.
