As I keep saying "best" is subjective. It is a personal choice.
What is the best car?
What is the best sports team?
What is the best religion?
The answer to your question is that the best distro is the one YOU like and with suits YOUR computer. You know that, I don't.
Try a few. Choose what you want. If you want Ubuntu, get that. If you don't like it, try something else.
