Newlisp is my favorite Lisp dialect. Before that I used Scheme and before that, CL. I prefer Newlisp because combination of dynamic scope and fexprs is conceptually simpler and more expressive than combination of lexical scope and macros. If reader doesn't believe me, he can check what Thomas Lord wrote on Lambda the Ultimate site, http://lambda-the-ultimate.org/node/3640

He really understood fexprs well. Or John Shutt's disertation. Or, this part of Alan Kay's interview: http://kazimirmajorinc.blogspot.com/2010/02/alan-kay-on-fexp...

Criticism of Newlisp? Well, yes and no - but, the point of every Lisp is, and particularly NL is - if something is missing, add it for yourself.

Picolisp is similar to Newlips, it is really minimal, very fast interpreter, written in assembler.

Other dialects have other advantages. But I'll stop here.
