I've looked at others too but honestly there are only so many brands that make both stylish and powerful laptops. I like XPS' design language and that their configurations are as powerful as they can put in a such package, but as I said, their quality control lacks.But that's one of the biggest selling points of PC.
You don't have to purchase Dell. There are tens of other OEMs out there
Razer is out of the question due to their warranty policies, I don't have any authorized repair shops in my country, that means I'd have to send it overseas if something goes wrong with it.
