What's the BEST laptop brand?

[CinnamonHearts]

I need to buy a new laptop, and I'm just wondering what's the best brand to buy for what I need it for.
Here's what I am looking for.
I want one that is great for multimedia purposes.
aka i want it to download movies and music quickly has well as play them back at a decent quality.
I want to be able to play games like sims without it being very slow.
and i want good internet speed because i spent alot of time on social media websites.

Serious answers only please, and I need reasoning behind your choices, as well as possible proofs.
after all this is my money we're spending.
I want one with a more durable shell, my acer is flimsy... D:
