I'm looking at 2 amps from Fosgate. The P500.1 and the R500.1 Both advertise 500W RMS at 2 Ohms but there is a $100 dollar price difference. Are the Punch amps really that much better than Prime or what?

I've only owned their Power Series of amps and subwoofers and they are amazing so I don't imagine Punch and Prime are far behind.
