Link has been my best character since Melee. I still love to use him, but I can't help but notice he isn't as potent a fighter he was in the last game. The trick with Link is to constantly incorporate your projectile attacks, even at close range. Shoot arrows at brawling opponents, throws bombs at rovering oppenents, and use your boomerang at close range to draw you enemy in for a charged-up smash attack. Link's other advantages are his "double-slash" forward smash attack and his long[er]-ranged clawshot grab attack. His disadvantages are, of course, his weak recovery, slowness and horrible lag, but these can be countered through the use of tactics. Think about a combo and then execute it, and constantly shield and roll to avoid the small pangs of damage which usually end up bringing Link down. It's also important to attack your enemy when recovering from a fall. Even though Links Up+B move lags alot, the option of charging it makes it possible to time the attack well, and this makes a lot of difference, because it gives you the chance to follow up with areial attacks combos. Items are also important to incorporate; not just to use, but to throw as well. I guess this applies to any character, but more so for Link, considering his weaknesses. Link works much better against single opponents, as he usually ends up collateral damage in Brawls, because of his lack of speed (a punching bag, if you will). For multiplayer, Link works the best in big stages (the Great Temple, for example, is perfect), where he can strategise, make good use of his projectiles, and avoid getting stuck betwen faster opponents.
