Do you prefer naans or chapatis/capatis with curry ?

That's a tough one.   I'd pick naan.   NO!  WAIT!  Chapati.  Definitely chapati.  But naan is good.  I can't decide which one because I love them both.

I like both, Mexican tortilla tasted best can be made with whole wheat

I prefer naan bread, 

Naan. It is easier to make. 

Of the choices, I'd have naans, but I do like paratha's.

My loose rule of thumb is naan with north Indian/Pakistani dishes and chapati with southern dishes.
