I'm not gonna argue with you about that. I haven't seen the upper tier output from COB vs that from HPS.
Although, I'm gonna throw a little musical analogy at this. I can put just about any shitty guitar in the hands of a great player, and it will sound like that player. Put some COBs in the hands of some of the best growers and see what they come up with.
As far as I can tell, there's a huge backlash against COBs but never did I see this against T5s, or CFL... and dudes were rocking perpetual CFL grows under 100W for years and although they may not have been massive kolas, it was top shelf dank no less.
