Maybe, however Razer's reliability is not noted for being the best. Personally, I'd far prefer not to need or deal with support.
If you buy the Razer from Amazon, you can then add on Amazon's warranty service and any issues you go through them and not razer.
I think that gaming laptops are better off if they are thicker.
The trend recently has been thinner, and yes, Razer has been leading the charge, but I will say that I'm getting really good performance and decent thermals out of Razer. I have it tweaked via Throttlestop, so I can balance performance and heat.
I think nearly every gaming laptop is going to have loud fans, there's no getting around the need to evacuate the heat, but I think for its size and performance it runs pretty decent. I wouldn't want it on my legs w/o a lap desk, but the keyboard deck is comfortable.
I was looking at new gaming laptops, and I was leaning heavily towards the Legion as I mentioned above but I'm not at a point where I need a new gaming laptop, so I largely put my research on the back burner.
