Because there is no dance partner company party I would like to perform Latin dance solo, please help me out with the cha-cha better or rumba or samba?

For men, the cha-cha is better. The samba or rumba is fine for women. Men's explosive power is better. Cha cha looks clean, women dancing rumba can show soft, samba is passionate like fire. But samba is very difficult to manage. To be stable at the same time passionate and exuberant. Still recommend rumba, you can show more.
