There is something so genuine about Sephardic davening. I was most exposed to it in Bombay. (I once was in Bombay on Selichos on Motzei Shabbos in the original old Chabad House of R’ Gavriel and Rivki הי’’ד.
I guess if I had to put my finger on it, it is the constant involvement of individual Mispallelim (or should that be Mitpallelim) and less of a focus on the Hazan.

There is also more audience participation, from all types, and there are colours other than black.
Certainly beats the rushed reading of the sets of Anenu’s, as you hit the home stretch before finishing.
