Xbone. I'm upgrading before the summer is out as well. If you flip straight from 360 to Xbone, your characters are saved, just gotta download Destiny and stuff. You do have to buy the disc Destiny again, but the DLC should be free (my best friend got screwed and had to buy the DLC again, but he's rich ¯\_(ツ)_/¯). Also, the GameStop offer currently going on is that you can trade in a 360 for 150$ credit or so towards an Xbone. Might as well buy the MC edition. Also, buying an Xbone should grant you a 40$ GC (check on that I may be wrong), which you can use to purchase Destiny or save for TTK. All in all, in stick with Xbox. Plus if you need it, I'll be there with you by summers end! Take care man.
