Get an Xbox One. The PS4 better graphics are not that noticeable. Right now backwards compatibility is only for Preview Program members, and will be out in the fall time, and right now there's not that many games yet. But your Destiny character will transfer over to the Xbox One, and you can also transfer your character from the 360 to the Xbox One, or PS4. But I don't believe your progress from the Halos will transfer over to the Master Chief Collection, but I'm positive that the older Halos will be in the backwards compatibility in the near future. And don't listen to the people who hate on, and say that the Xbox One is a "sh!tty console", because it's really not bad at all, and I actually like it better than my PS4. I hope this answered your questions.
