I've been unfortunate enough to be DDOS-ed on both linode and digital ocean for some of my sites. suffice to say, linode handles the ddos much more gracefully than digital ocean. digital ocean promptly bans you for TOS violation and locks your account after 3 DDOS attempts. I know most people don't have sites that are DDOS-ed often, but if you do run that risk, just know that digital ocean will most likely have you moving pretty quickly.
