As gaming laptops, Alienware and Razer Blade 15 are both wonderful options. They are mainly different in the outlook and GPU configurations. If you prefer a minimalist style, you might like Razer Blade 15 instead of Alienware. However, Alienware provides optional Intel Core i7 and i9 while only Intel Core i7 is available in Razer Blade 15. If you want Core i9, Alienware is better for you.
