Smarty is decent enough. Out of the different template engines in php, it's the only one ive found that is decent.

Good enough in fact that myself and another developer made a push for moving our site (which would be considereda BIG enterprise site) to make smarty standard.

While the whole site is not migrated to it, we forced all new development to be done using smarty, as well as changing over any old applications that we needed to do major work in.

It's helped a lot, and our customer experience team (who are responsible for look and feel aspects) are very happy with it as well since they don't have to bother with looking inside actualy code, or giving the programmers the design to shoe-horn in
