It depends on the condition of the runway and airport regulations. Some airports dont allow thrust reversers during normal opperations due to increased amounts of noise.
If the runway is contaminated with snow/water, using reverse thrust is usually the safest method because the brakes will not be as effective due to the loss of traction.
When thinking from an economical stand point, it is better to use the wheel brakes as they are cheaper to maintain than the thrust reversers.
Remember that during aircraft certification, the landing distance is measured without the use of thrust reversers.
