Not surprised dat you get no answers, brah.

Not really that good a question..

Ah dunno much about hps. Use LEDs myself.
But "which is best?"
Only real answer you gonna get is; "depends."

What strain? Is a biggie.
Some need mo' intensity dan odders.
What kind ventilation? 50% mo' heat wit 600W.
(Actually it's a bit more, but that plays against efficiency in lumens per Watt).
How much headroom?
Top floor?
Mebee got problem wit FLIR.
600W more likely to get knock onna door, yeah?
Hydro?
Dirt?
Whattaya pay per KWh?
Light leakage a problem?
No want funny yellow color spillin' out.
Mo' betta use CFL when neighbors might see.
Dey gettin' betta an' brighta alla time.
(Da lights, an' da neighbors)
Rollin' in dough, or got plenty spare time,
anna sense a humor?

L. E. D. (Warning, rocket science, it ain't, but ya do have to pay attention. )
Also, it cost a bundle even when DIY.
But, you can lay a carpet of "targeted" energy on a plane. 1" from da girls heads when ya SCROG.
There's little heat and it's easy on your 'lectric bill.

Grow's slower, an' got funny colors, so, not fo' everyguy.
So, when you read all dis mountain of stuff, you know what be bess fo' you, yeah?

Good luck brah!
