Yeah, don't even compare them. This whole "Sonic vs. Mario" deal came about solely because of the Nintendo vs. Sega console era. Now that Sega has stopped making consoles-they're even making games for Nintendo!- you may as well be asking something about apples and oranges which someone mentioned, only where they're both apples and you're asking "which is the better fruit, Sonic or Mario". Where Sonic and Mario are both apples. Oh, and the Sonic/Mario "war" can just never be mentioned again because nobody over 12 (obligatory age of course) enjoyed them. In other words, G(row)T(he)F(uck)O(p)U(p). No personal offense intended.
Also no random responses. Just because random responses are no longer funny but instead unfunny. You can choose some crazy other thing that is completely out of the scope of discussion and mention it, but we all can. Or you can self-assault and perhaps pretend that you get involved in some zany antics in real life while in reality, you get involved in some standard-issued non-antics and again, so can everyone else. Or you can ramble monotonously and use minor verbal puns in a repetitive posting styles but once more, so can I and, in this case, am.
