Hello and welcome to the forums
As for Apple,although its expensive but they offer excellent battery life
For HP,Toshiba and MSI it mostly depends on the model that you are considering.
Overall you can't say which brand is the best because it really depends on the model
As Maziar said, model is more important than brand. A brand with an otherwise lousy rep may have a stellar model that goes against their norms. Apple has quality engineering so you always know it'll be a reliable machine, but they are indeed expensive. Roughly 2x to a PC model with the same hardware. However you also get a lighter unibody design and longer battery life. Why don't you tell us what you'd like your laptop to do?
