Dialga is on the Diamond box and Palkia is on the Pearl box, and that's only the start of the Pokemon Diamond Pearl exclusives. Each game has 20 Pokemon the other one lacks, from Tyranitar on one side to Salamence on the other, so it's worth knowing which ones you're giving up before you buy.
The Sinnoh story, the Gyms and the Elite Four are the same in Diamond and Pearl. Only the Pokemon change, and anything you miss takes a trade.
Which Pokemon only one version has

Diamond has Scyther and Scizor, Larvitar all the way to Tyranitar, Aron all the way to Aggron, and Murkrow with Honchkrow. Pearl has Bagon through Salamence, Spheal through Walrein, the Slowpoke line with Slowking, and Misdreavus with Mismagius. The two ancient Pokemon split as well, with Cranidos and Rampardos in Diamond and Shieldon and Bastiodon in Pearl.

Your version's legendary waits at the top of Mt. Coronet, on the Spear Pillar. Dialga is there in Diamond at level 47 and Palkia takes its place in Pearl at the same level. That's the only gift or fixed Pokemon that differs between the two games.
Roark, Gardenia and Maylene are the same

Roark opens the Gym route in Oreburgh City with Geodude and Onix at level 12 and a Cranidos at level 14. Pearl players get that Cranidos in a Gym fight even though only Diamond lists it for catching. Gardenia is next in Eterna City with Cherubi and Turtwig at level 19 and Roserade at level 22, and Maylene follows in Veilstone City with Meditite and Machoke at level 27 and Lucario at level 30.
No trainer team, shop or item list differs, and the road to the Spear Pillar plays the same in both.
Which one should you pick?

Choose Diamond for Tyranitar, Scizor and Dialga. Choose Pearl for Salamence, Slowking and Palkia. (Pearl, because Salamence looks like it enjoys itself.)
