Using HPS During Veg Stage

I was thinking of trying my 600 watt HPS as a Veg for my next string, only going to be growing 6 in a 6x6x8... I only have a 400 watt MH at the moment... would I be better off vegging with the MH @ 400 Watts, or the HPS @ 600 watts. No I cant use both at the same time unfortunatly. Thanks!
Less stretch, better leafing with MH compared to HPS watt-for-watt. MH is less efficient watt-for-watt as well. The 600 HPS wins this one due to much higher output.
