Based on what exactly. You have Oliva a former olympic lifter disagreeing with you. Me i find it easier to get intense on a machine, because going to failure doesn't carry as much of a concern about getting stuck with the weight or balancing it vs. just getting the weight up.
Everything I could say would be anecdotal and you could refute, and we could go back and forth. If you are talking just lifting heavier, I would say most men could build a thicker stonger overall body with compounds.
There are other intensity techniques, which you tout, that machines can be more useful for...example, HIT that Oliva liked. I would never go to complete failure on Olympic cleans. I would say that his Olympic lifting background, much like Coleman (mostly for football and PL) made there later lifting techniques all the more effective.
