What are you trying to do? Are you programming for a mobile device or a desktop platform?

From this page:

"OpenGL ES 1.1 is defined relative to the OpenGL 1.5 specification" and "OpenGL ES 2.0 is defined relative to the OpenGL 2.0 specification".

As far as I know the biggest difference between the two ES:s are shader support. E.g. the iPhone supports 1.1, and thus does not support shaders.

If you want a list of the supported functions you have to choose an API (ES or desktop) and a version. Eg. here is the list of functions for ES 2.0.

I don't know about any list that compares GL ES 2.0 and GL 1.4. Feel free to make one and we'll upload it.

Compatibility issues? Context creation is not crossplatform in OpenGL for some reason.
