On one of my Asterisk 1.2 setups, I have a dialplan that mixes both - so
they can coexist in the same extensions.conf.
The difference is that with the "n" type extensions, you can easily
insert a line or three without renumbering lots of lines - and searching
for all those GOTOs that also need a new line number. Renumbering
error-prone.
An advantage of numbering is that the line order is not important,
because of course Asterisk would select by number, not order - and
possibly (although I did not investigate this) including _parts_ of an
extension from another context might work better.
All my new extensions use the "n" style, but I am not going to rewrite
the older parts of the dialplan soon.
