which build are you taking?
what are the specs of each laptop?
between an i5 and a ryzen 5, they'll be... around equal
intel will probably be a tad bit better for gaming and the same or a lil slower in workstation tasks.
As i said earlier, i have helped to purchase both of these laptops for relatives so i have some experience. The nitro 5 is better, but the 505 is still pretty good.
