That's just a public list, essentially a popularity contest; note that Mario is ranked #11 while Dr. Mario is #39. It will still take some time before accurate commentary can be given to tournament viability, especially when you consider things like custom moves and banned stages.
Incidentally, I have virtually no idea how to fight Sonic. I only see him online on occasion and his playstyle is so wildly different that I just wing it. Still not as bad as fighting good Lucarios and Little Macs.
