The problem people run into comparing the two is that bodybuilders talk numbers that they can repeat for a set of 6,8,10 whatever and powerlifters talk singles. There are heaps of bodybuilders who can lift the Ausbb magic numbers but don't know it. They have never gone below 6 reps in their life.
When I did concentrate a bit more on strength a few years ago I was surprised how quickly my squat and deadlift went up. I could obviously already lift a lot more than I thought, I just had to get used to the weight and build a bit of belief.
Linear progression is a great logic but it works more quickly for one rep sets than it does for ten rep sets. You won't lift your ten rep squat by 180kg in 3 years.
