Here's my favorite team (to make things more fun, I don't use my starter pokemon).
-Vileplume with Solarbeam (use TM), Petal Dance, Poisonpowder, and Cut (use HM).
-Raichu with Thunder, Thunderbolt, Quick Attack, and Flash (use HM).
-Flareon with Fire Blast (use TM), Flamethrower, Bite, and Sand Attack.
-Pigeot with Steel Wing, Wing Attack, Sand Attack, and Fly.
-Haunter/Gengar with Shadow Ball, Shadow Punch, Hypnosis, and Dream Eater.
-(Most important) Gyarados with Hydro Pump, Dragon Rage, Hyper Beam, and Surf.

Both Pokemon Diamond and Pearl have Team Galactic as the main antagonist team.
There is no "best" team. Just get many Pokemon with good abilities and attacks and put them in your party, if you train them very well you will have a "best" team.
