I'm going to play devils advocate here and say go with soulstorm.
I don't quite get all the flak it receives from fans, having played both Dark Crusade and Soulstorm. The only complaint I have with SS would be the Sisters of Battle infinite resources exploit/bug/feature.
I can only assume you are NOT buying this game for it's multiplayer because... well, last I checked multiplayer was a ghost town in the DOW 1 games.
Soulstorm: you get all the races (Except tyranid, but there's a mod for that) more units (The flying units are a bit wonky, but entirely optional. Don't get the hatin' on those either)more maps, and new tech/units.
Dark Crusade: Better campaign. Less of everything else.
Make your choice.
