I've read comparisons between smartparens and paredit, but I haven't found the case for smartparens compelling enough to switch. Are there any features in smartparens that paredit lacks that you feel you can't live with out, or make your life easier?
Smartparens is actively maintained, which for me is an attractive "feature" when evaluating any tool that is to find a prominent place in my workflow. Also, its extensible design allows it to be used with languages and data formats other than lisp/scheme dialects, so it has a broader reach than paredit.
As for wrangling sexprs in, say, Clojure, I think paredit and smartparens are one equal footing. I still stand by my original statement inasmuch as I think smartparens is a worthy successor to paredit.
I haven't yet, but I intend to when I get some time. I was hoping to find someone else to give me an opinion on how it compared to paredit and smartparens, before I tried it out :)
