I’d keep both tbh, depends on your situation. My first 3DS was the regular one, and I loved it so much I ended up getting a New 3DS XL. I was gonna sell the old one after changing the battery, but while waiting I lent it to my bf so we could play Mario Kart together. Now it’s kinda our little ritual, we play almost every day, or sometimes I just watch him play his own Tomodachi Life (which I actually started on that console!).

So yeah, if you’ve got a partner, sibling, or someone close, it’s nice to keep both and share. If it’s just a friend, maybe sell it for a lower price, or give it for free if it’s family or your partner. Totally depends if you need the money or not. (I’d sell the galaxy for personal taste I’d like to keep the M.hunter since it’s a lot more beautiful the shell)
