I don't understand
What will be more sustainable

Shadowsocks is basically a proxy to bypass Internet censorship, while 3x-ui is a graphical interface that helps you manage Shadowsocks servers easily. In the long run, Shadowsocks is more sustainable because it focuses on privacy and encryption, so it does not rely so much on external tools such as graphical interfaces...
