Well somewhat amazed I missed this one going on. Interesting points and counter points. I'll stay clear of any bb vs pl debate. Im obviously biased. Interesting discussion though. and lively. Of course many of the top tier bodybuilders have powerlifted. Including Arnold, but thats something lost to history. You pull up Louie, or Mark Bell, and I'd counter with Stan, or Frankl. But I'm seriously not interested in joining that portion of this thread.
For the record I train 3 days a week and typically each session is 2-3 hours, although squat is normally closer to 4 hours. That's preparing for a equipped competition. With a full powerlifting team. The average powerlifting total of our group is 2020 lbs. (prior to this sundays XPC competition when that average will go up)
When training Raw only (no gear) my sessions are still at the 2 hour mark.
In fact looking back very rarely do I have a session at or under 1 hour in duration. And I have at lease a four year history where I can say prior to any hormonal assistance of any kind I averaged an increase in my total of 100lbs a year, and an increase of roughly 10 lbs of lean body mass. So obviously I feel my methods and duration/intensity work for me. I have never stopped to worry about cortisol levels.
So anyway, back to this cortisol discussion. The long and short seems to be that short spikes in cortisol as it relates to weight lifting is probably beneficial. It's the prolonged cortisol that creates the issue right? I think that my works constant stress and screwed up hours elevate my cortisol which can be a huge stumbling block to fat loss goals, but I'm not sure about its effects on strength. I think like all the rest of the hormones it's tissue dependent. At the end of the day, I think it's a fools errand to single out one specific hormone and say "hormone X" always acts in this manner.
Recently read about using Phosphatidylserine at bedtime to reduce high cortisol levels and improve sleep. I tried it last night (300mgs) and had deep uninterrupted sleep. Don't know if my cortisol levels are high, though there's a fair amount of stress at the moment.
So if if you're suffering from prolonged cortisol levels as Macdon mentioned, maybe this is a way to combat them.
Although it's a bit dated now, Robert Sapolsky's "Why Zebras Don't Get Ulcers", Why Zebras Don't Get Ulcers, Third Edition: Robert M. Sapolsky: 9780805073690: Amazon.com: Books, imo is the best lay guide by a first rate bio-neurologist to the action of glucocorticoids in general, and cortisol in particular. I don't recall that he says so in so many words, but it's clear from his account that it is chronic, not episodic, cortisol imbalances that create problems, including many of the chronic diseases characteristic of our "civilization".

It IS good, but be forewarned, it ain't easy. LOL

Interesting notion that prolonged not episodic effects are different.
