A:Answer Hey there John. The Lenovo legion 1, the older version of the legion 2 is overall weaker in power, display, and comfortability. The legion 2 offers a sleek design allowing you to play for multiple hours without discomfort. The new Ryzen Z2 chip is capable of pulling frame rates the legion 1 could never imagine of. The display on the legion 2 is a slightly smaller OLED display, which the legion 1 did not have. The legion 2 also has better battery life capabilities.
What I would suggest: Buy the legion 2 if you plan on playing high end games, and want better performance. If you’re a casual gamer, then I suggest buying the legion 1, as it is cheaper.
Hope this helped!
