Conclusion
The ubuntu-linaro is a little bit more fast, but it'snt a big difference.
I prefer to use raspbian cause it has a big community, and the information it's easy to find, and may be it has more things that I need, but I feel comfortable in raspbian than in ubuntu-linaro.
But I know that I'm not taking all the power of the cubieboard, I've in mind to improve the compilation using cross compilation, and take advantage of the NEON acceleration, but I'll do latter when I've more knowledge
