They are both great games. Only you will know which one you would like better.
I had a ToM for several years. While I liked it a lot, I was just getting a bit bored with it.
I sold it and filled its spot with a TWD Premium. So far I am very happy with the switch. TWD is a great game. A real adrenaline pumper. ToM was much more of a relaxing game.
I can't say which one is better - just different. I was finished with ToM after a few years so it worked for me.
Good luck.
