Tom vs Adam vs Lucas

[Silver Doe]

Lucas, then Tom, then Adam.
Lucas because he's the most interesting of the three in my opinion with his Russia background (I don't mean series 9 Lucas, because it was awfully done).
Also I started watching with series 7 so he's "my" Spooks hero and I relate to him the most, I like the way his character was built more.
But I like Tom almost as much, very deep character.
I liked Adam in series 3 and 4 but he annoys me so much in series 6 that he has to be last on my list. I also think we see too much of him, particularly in series 5 and 6. With Tom and Lucas, we see more of the other characters.
