SSBB Cpu or Human?

I've played a lot of SSBB in my time, and I must say that ,without a doubt, I prefer fighting Humans. Not just because you feel more rewarded when you beat them as you have proven that your skills are greater than theirs, but also because I find them more believable. Humans can make mistakes and they can also fall into rhythmic patterns of predictability in where you can expose their weaknesses and win through more strategic thinking. Cpu's on the other hand are almost perfect. Level 9's frustrate me a lot. They seem to be able to do things which no human player can actually do. For one, I've seen them shield and then un-shield faster than any human could press a button, but the most frustrating thing I find is that they have this tendency to do super fast grab attacks, often while I am executing my own moves. Grabs are very useful in a fight as they are quick and do a fair bit of damage. 


I  use the gamecube controller where the grab button is positioned very awkwardly. Can you see the "Z" button? If you can, then you will probably notice that it's not easy for me to grab, seeing as I also keep my finger on the shield/dodge button as well. Yes, I can beat level 9's. Yes, I beat them a lot, but I actually believe that fighting humans is easier. I like to find out what tactic's they rely on and expose their weaknesses and strengths. I'm not used to losing to people in SSBB (I'm not trying to boast, and I admit that I have been beaten many times over the years) I just find playing against human's more fun.
