I’m going from experience, I have a tent with Budmaster GOD’s and one with 6 QB’s they perform similarly watt for watt, although the GOD’s were far more spendy.
No doubt QB’s are tip top, but...... top quality blurple will give them a run for their money although the cost will be a fair bit more for said blurple.
I’ve done loads of ugorg stuff, mostly coz I was caught up in the hype of everyone on that site wanking over them,
They are no better and no worse than any other seed bank in my opinion.
