Yes, another one of these threads just because I like the insight and depth a lot of you go. "Rules", Crysis 3 and prior and Halo 4 and prior. Canon details only. Just Master Chief (no Blue team, or other Spartans involved), and just Prophet (no Pyscho). Due to the fact that Prophet is no longer just Laurence Barnes, and is now part Alcatraz (though still predominantly Laurence) you may use details on Alcatraz as well as Laurence.

*This thread isn't specifically versus in the sense that they would be fighting, it could be who you like better and why, whose stronger, better in a certain situation, etc. Whatever you make of it. Keep it classy.
