"Either way i intend to use smarty partly because i have lots of experience with it and partly because its much more well documented and has much more functionality than blade and to me the syntax is slightly cleaner than twig although the template engine is not the point of this question really"

"If your in the market for a templating engine twig a new templating engine used by symfony is much better than smarty imho"
