electric-pair-mode offers a tiny fraction of the features of paredit.
The later takes some time to learn, but in my experience the effort
pays off if you work with lispy languages.
FWIW (he ducks), I work with a Lispy language, Elisp ;-). And I
don't use any "structured-editing" feature (crutch / ball-&-chain)
such as `paredit' or `electric-pair-mode'. I'm non-electric all
the way.
I use only (1) the usual keys to indent, move over & around sexps,
transpose sexps, etc.; (2) `show-paren-mode', `blink-matching-paren';
and (3) (yes!) sometimes a mouse (double-click sexp select,
copy-kill-yank).
I've never had any problem with unbalanced parentheses, brackets,
braces, angle-brackets, double-quotes, etc. Really_not_ a big
deal, IMHO.
To me, having an editor automatically insert a closing delimiter
each time I type an opening delimiter is a bother, not an aid.
