Good comparison. I think Antonio Margarito, Brandon Rios, and Leo Santa Cruz were also very similar to each other stylistically as well.
Paul Williams was more of an awkward, high volume southpaw who didn't fight tall. Margarito, Rios, and Cruz threw lots of punches too but they weren't as unorthodox as Williams. Hard to find a comparison to someone like Williams who had a pretty unique style, as flawed as he was.

The Kronk style through and through I didn't see it yet but Marquez and Ricardo Lopez (both Nacho's craftwork) Currently: Frank Martin is a less physically imposing version of Spence.
