what would be better

I am a new grower with only a few outdoor grows never tryed dwc indoors so this is my first go at it.
I have a 5x5 grow tent and want to go with leds just to save some on heat and power. I have narrowed it down to 2 companies Apache tec AT-600 or 4 a-51 xgs190. Plus and minus which would be better for a new grower.
thank you

The AT-600 would kick as in a 4x4 but for 5x5 the XGS's is the way to go,more total watts and a more even distribution of the light. I just set up a 5x5 tent with 4 XGS's.
