DC. He already had the UFC belt, a SF HWGP belt, KOTC HW championship, and some weird Aussie regional HW belt (with a defense against a name opponent), and was FOTY all over the place as a HW in 2018 after beating the best UFC HW. Idk that at this stage there is much Jones could really do to trump DC's HW accomplishments. There's not enough top tier competition left at HW for Jones to build a resume that would really wow anyone, and we don't know at this stage if Jones actually wins any fights at HW.
