Well prime prime just lost his last fight so he isnt prime anymore and just prime hasnt lost yet so we dont know when he will reach his prime and prime prime prime was only in his prime for 1 day before that he was green and after that he was past his prime.
'Slightly past prime' is always more skilled and fights smarter than 'Prime' so I take choose them every time.
If only prime had the prime skills of prime prime, even prime prime prime in his physical prime would have had trouble.
