I can suggest two points:

- Lexical binding is closer to the how bindings work in contemporary 
languages, or ones that are most popular these days anyway. Which makes 
transition easier, and so helps with writing and  debugging new Elisp.

- The "lexical binding" dialect of Elisp is easier to analyze for the 
byte-compiler. Not just in terms of performance, but to offer warnings 
about potential typos. Such detection won't work with "dynamic binding" 
Elisp: any variable with a weird name can be intended to be bound in the 
caller.
