Personally, it'd be a tough choice for me to make. I like both (I'm not a huge Samsung fan, but I like the Edge series). I feel like I'd go with the 10 in the end, however.
But it really boils down to what you prefer, and how you'd use the phone. The Edge is awesome and has many great features that the 10 doesn't (ie, better camera, edge notifications, etc); but the 10 has OS improvements and its camera has gotten a lot better now!
If you're really torn between the two, y advice to you is to watch unboxing reviews on YouTube (check Android Authority and Android Central) and check out the phones in the store so you see how they operate. Be sure to choose the one that you want, because at the end of the day, we can only give you suggestions; but you get to make the big decision! Good luck, and let us know what you choose!
