Even though I am a big COD fan I can tell you this...
Titanfall is faster, almost constantly faster.
Even with bots you still got faster gameplay.
You can run cling to walls , hop up on walls and bound over roofs.
You can load up into a Titan and swat other smaller players.
You can jump on top of a Titan for protection shooting other players.
You can take out a Titan but pulling off its top and shooting the top.
you can have your Titan follow you and fight be your side.
You can explode a Titan to take out every enemy round you.
Nothing in Titanfall is overpowered. Everything has its counter.
You can kill the enemy players before they reach their retreat ship.
You can destroy the retreat ship before it leaves.
And thats off the top of my head.
In COD you can shoot the players that come around the corner and run around the map.
You can... cant think of anything else.
I though Titanfall would suck but after playing it I realized it didnt.
