I honestly don't think the Switch could handle either of them..Especially since I remember back when the Prequel came out for the PS3, it could barely handle it, and I'd get frame drops Alot. Not to mention that I heard, and seen reviews that the Switch can barely handle Overwatch, and Borderlands is alot more taxing.
if it could handle it. borderlands 2 all day. maybe they'll make a switch pro. I thought the switch had similar hardware to the Xbox 360.
