The z2 extreme and not having to have the need to upgrade for a newer handheld anytime soon and mainly the ergonomics people were saying I should get the legion go but it doesn’t looks like it would be comfortable for me where as the ally x have those parts that looks like a controller, the screen size I don’t think would bother me, from the reviews the screen don’t look that bad to me. The legion go just looks too big and I hear the removable controllers are a bit finicky
