Which template engine do you use..?

Just to put my two cents in:

Templating:
Pure PHP
I already have to know HTML, JS, CSS, PHP. Why should I need to learn another language just to output something my programming language already can?

Curly Brace:
New Line
I can basically scan the left hand side of a file and know exactly where everything begins and ends

Inside View:
if...endif, foreach...endforeach, etc
I think it looks cleaner. When in a view, I expect to see HTML markup. I know logic is there, but it breaks the flow to see lots of curly braces


And just for an extra cent or two:

Indentation:
Tabs
I prefer to hit the right arrow key once over having to hit it 3, 4, or 5 times to get to the same place.

IDE:
vi / vim
Comes standard on Linux / Unix / Mac, and PortableCygwin makes it free on Windows as well
