i don't think the brand has too much influence on the laptop itself even, the internals are made by the same companies anyway, its just that one might be bit more rugged, overheat less or have better power supply. even then, it's hard to say, as it mostly differs from model to model (and price), and not brand.
but we can't recommend you anything without you being specific about how much you can spend, what do you need in it, what are the models that you can buy, etc.
