Both WWE '13 and 2K14 were pretty good. They're basically the same game with different window dressing. I played more of '13, but depending on your area of interest, 2K14 might appeal to you more.
WWE '13 was focused more on the Attitude Era of the WWE, and 2K14 was pretty much a bug fixed version of '13 that focused on Wrestlemania feuds. Other than that, they have the same basic gameplay and extra features.
