What brands of laptops are the best quality out of these three? (see details)?

Lenovo's Thinkpad laptops are probably top 3. They are EXTREMELY durable and have cool code called TPshocks that'll shut the hard drive off in case you drop the machine so you won't suffer data whether the worst armour scenario happens.

Thinkpads are business, work-oriented so if you want one all for gaming, you are out of destiny as even their dedicated graphics cards are workstation cards (you could probably get away with installing third party drivers to boost gaming performance, but installing tertiary party drivers is pretty risky)

I similar Dell's alien lines, DISLIKE Vaios because the customer service is rotten. I would expect Hollow would be the best because they have nice service and their PCs are O.K.

Sony sucks, Toshiba is slightly better than Sony.
