Are cuban cigars really the best?

[T.G]

Are CC's better?

"Better" is really a personal judgement, to some they are, to others they aren't.

One thing that they most definitely are is unique.
Just as Nicaraguan puros, Honduran puros, Dominican puros (etc) are all unique.
Each one of these countries produces tobacco with unique flavors and characteristics - you won't find Cuban twang in a Nicaraguan puro, no more than you will find Nicaraguan pepper & sheer power or Honduran spice in a Cuban cigar.

All you can do is keep trying cigars until you find the ones that you like - at that point, you have found what is "better". It might be a $2 cigar or $10 cigar. It's all about what you like, not what someone else likes, since you are the one smoking it.
