Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
Plas has by far the greater durability
Buddy has the greater versatility
I'd say Plas takes it because Buddy really isnt doing him much damage. Even the sonic attack of a pistol shrimp isnt doing significant damage to Plas' elastic ear drums.
