Standard Vs Enhanced Performance bulbs

I have a 430 Watt HPS (Ansi S145) and a 400 Watt convertible ballast that I plan to set to MH for full spectrum lighting. This is for a flowering room, and I may go all HPS for late flowering. Should I buy the Hortilux bulbs or is the enhanced spectrum redundant and unnecessary having both lights? Price differences are $50 to 125 for the MH and $35 (400 Watt) to 95 for the HPS. Note, I don't think they make a standard 430 Watt HPS only the Hortilux. I'm okay with a standard 400 in the 430 ballast, but I expect shorter bulb lifespan.
I value and appreciate any input.
