I think that all the characters are good fighters, it just depends on how well you use them with their builds. Not all the people knows how to use all the characters. I normally use Cloud as my main character because his attacks are very powerful and are easy to connect. I like his ability to wall rush the opponent with his powerful blows and his HP attacks are extremely awesome. My personal favorite attacks are Omnislash V.5 and Finishing Touch. I also like his epic alternative custom, which is the best looking alternative custom of them all.
