For an LEMP stack installer, my vote goes to CentminMod. centminmod.com/faq.html Both EasyEngine and CentminMod's LEMP stacks perform much better for Wordpress than ServerPilot in terms of load handing and loading times from my experience, but unlike EE, CMM's developer is very active provides absolutely amazing support for a free installer. It also offers some security features lacking in EE. What do you use ?
