template engine: twig, dwoo, smarty or CI parser?

[eluser]Aken[/eluser]
I use Smarty on my website. Granted I haven't tried any other ones (I probably will now), it works pretty well. I haven't noticed any terrible speed issues (I use CI's caching on top of it, so once cached it's super fast regardless). It does seem a bit bloated for what I use it for, but it works, and my site isn't heavily trafficked at all, so whatever.

I have some code on GitHub for basic implementation of Smarty into CI: https://github.com/cryode/CodeIgniter_Smarty
