I brought that up that (Luffy/Admirals) reference because I wanted to point out that whether that was only Garp/Sengoku or they both it would not have mattered. I mean, if a guy who is strong walks up to ttwo people who are stronger than him, he can still fight them and eventually lose. That is true if there is one opponent too.

I my opinion, Shiki in his prime, (before loosing his legs and possibly before he got his wheel attachment was on par with Sengoku but weaker that Garp) which implies by default that in my opinion Garp in prime was stronger than Sengoku in prime. However currently they are even as Sengoku is younger than Garp or at least that is what I believe. In my blog about power levels from before the issue was banned. I rated them as follows: Garp: 96/100 (prime) 91/100 (current); Sengoku: 93/100 (prime) 90/100 (current); Shiki: 93/100 (prime) 86/100 (current).
