Are subs fundamentally better when toasted? (Remember those great Quizno's ads?)

I had half of a toasted Italian sub at the airport the other day, and it was delicious.  It reminded me of a great sandwich place I used to go to in Richmond 15 years ago, but I can't think of the name at the moment.

Regardless, I don't think there was anything particularly special about this airport sub, other than the fact that it was toasted.  Which leads me to wonder, should I be getting all my subs toasted?  I go to Subway from time to time on my way to work and I've never once asked them to toast my sandwich.  Am I missing out?

I haven't actually been to a Quizno's, but this train of thought brings back fond memories of their spectacular commercials from 2004:
