It depends on the game, however, I generally enjoy the Dawn of War/Company of Heroes style of resource gathering more than the Starcraft/C&C style. DoW and CoH get you out on the field, capturing, killing and scouting immediately which keeps the game interesting constantly. Starcraft and C&C/RA tend to have an ebb and flow of activity with periods of action, expansion, researching, and then the "Final Battle". Dow/CoH kind of battles that ensue tend to be spread out on larger fronts with fewer units until you gain an edge over your opponent.
