Love both equally
GOT is generally better directed with less filler, while I think TWD is largely more satisfying on a character-driven basis (ie: Rick would have died in the Season 1 or 2 finale and we wouldn't feel close to any of his group at this point given half of them would be dead by now if it were more like GOT).
Also, Season 6 episode 9 is the best episode in both series
