3 Hour Nitros vs 3 Hour Raws?

What do you think is the main reason(s) it was (seemingly) much easier to get through 3 hour Nitros,(except maybe towards the end), then it has been getting through 3 hour Raws?  Creative, talent, wrestling style, etc., all were better during that period with WCW, or do you believe it's a rose colored glasses type deal?  

I never watched the 3 hour Nitros and I don't watch the 3 hour RAWs now so I'm not really a great judge of that one.
