As someone who switched from Xbox to PS, I enjoy my time much more on PS. The player base is much more mature on the whole with far fewer annoying/toxic gamers from my experience. If you love Halo that much, then keep playing on Xbox, but each Halo since 3 was mostly disappointing for me and not worth sticking with the console. I had jumped from PS to Xbox for Halo years ago because it was a great series, but I don't feel that strongly about Halo any longer.
