Nothing I think. According to the docs:

To start a root shell (i.e. a command window where you can run root
commands), starting root's environment and login scripts, use: 
        
sudo -i     (equivalent to sudo su - , gives you roots environment configuration)

To start a root shell, but keep the current shell's environment, use: 
        
sudo -s     (equivalent to sudo su)
