The way you phrase it, you already played it on Xbox and wonder whether the PC version is any different, correct?

To my knowledge, the PC version is the same, but of course you get to play with mouse and keyboard if you so choose, which can be quite a drastic improvement.

If you liked it, make sure to also check the latest sci-fi Call of Duty games, i.e. Black Ops 3 and Infinite Warfare. They also feature tons of navigational tools like wall runs, double jumps and zero-gravity combat, the design is not as strong as Titanfall 2 but they are still superb pop-corn campaigns.

If you're worried about continuity, they are totally independent. Black Ops 3 vaguely references the previous games but happens decades in the future.
