While the multiplayer of Titanfall' does share some aesthetic similarities with Call of Duty likely due to the developer team, the gameplay is completely different from any Call of Duty''.

The average Call of Duty focuses on linear maps with run-and-gun gameplay, broken up by killstreaks and the objectives in a variety of gamemodes. ''Titanfall' has larger maps, with a greater emphasis put on the freedom the player uses to get around, broken up by David vs. Goliath style fights, from the Titans themselves.

Neither of them are "better" since that's purely opinion and there's no right or wrong, but I feel calling it a CoD-clone is a little unfair considering the differences.
