Best Free to Play game? Yes
Best FPS? Very Possibly
Best PC Game? IMO, Definitely

I absolutely love TF2 and all of the uniqueness it contains. The classes are all balanced and have great personalities, the weapons are not too overpowered and usually the beast weapons are the stock weapons, (The ones you start out with) and for crying out loud, THE HATZ! Hat Fortress 3 confirmed! All joking aside, you will most likely fail in finding a more balanced game that can keep you playing for hours. Plus, the only advantage others can have on you is experience, not weapons or cosmetics as they are not overpowered/have no effect on gameplay. And the community, it's huge. Fo

or a game that's seven years old, it still has a hundred thousand people playing it every day. (Only game it is surpssed by is Dota 2) Plus, the community helps benefit the game as they create weapons and cosmetics for use in the actual game, resulting in constant updates every few months. Although there is no actual story, the game is a hell of a lot of fun to play and you'll start wishing why you didn't play this game earlier.

Oh, but that price might seem a little steep, OH WAIT IT'S FREE!
