what 1000 watt bulb is best?

i have a HORTILUX METAL HALIDE BLUE 1000 watt
im using it for veg right now my friend thinks if i use that same bulb for flowering i will not produce high quality bud and instead should use a HPS
below is the light spectrum the HORTILUX METAL HALIDE BLUE puts out is this a good range of spectrums for flowerings ??????
