I found the easiest to learn was c-script, very forgiving.
Lite-C on the other hand is like a stack programming system, everything must be in the right place, say the right things and do the right things when called or else.......SCREAM!
So Im slowly learning Lite-C now and while its not too bad, its not easy for me either, yet.

If your experience base lead you to c-script all those years ago then stay with c-script for now.
If you havnt learnt any scripting language then start with Lite-C.

If you havnt learnt any scripting but want to see results in projects that are meaningfull to you, use c-script, its got a wider learning and user base than Lite-C, more working demos and snippets and its easy.

Thats my call.....
