which is the better MH bulb?

so i was looking around for replacement bulbs and came across a couple PlantMax bulbs. One is in the 4900k spectrum and the other is 7200k spectrum. Which is better for veg growth the 7200 for tighter nodes?

7200 is much better

so basically the far ends of the spectrums are the best bulbs to use like 2000k hps is best for bloom
