Not too good at Tenkaichi games...

I'm not too good at the Tenkaichi games so I was just wondering...which one s easier? BT3 or Raging Blast 2? Cuz I get frustrated when I keep dying and I end up hating the game. I dont go online, i just like to do the story and then play versus mode against the computer. And i dont want the computer beating my ass lol. Even if im on the easiest setting, which im probably gonna put it on, will i still get served? Which game should i get? HELP!
