It all depends on the crop size of course. The HPS will give off more lumens, which will cover more space. Problem with the HPS is youll be spending more money than you would with the Fluros. Depends on your pocket really..The HPS lights are a lot hotter than the CFs..HPS is best for flowering. Fluros are good for veggin because during veggin you will want to keep the lights close to the plant to ensure youll get more compact buds and they wont burn the plants. HPS lights you cant put too close and this causes them to become tall and lanky, which will produce airey buds.

Totally up to you..
