Have not tried that one -- when I contemplated ordering it after liking Mile High, I read that they were similar enough that it wasn't worth having both (that's my recollection). Maybe someone else will chime in, but you might need a different thread to get their attention.
I have not tried the first Will Power & Grace DVD either, but I remember threads where people said they liked it better than Mile High. The first DVD was very popular at VF when it was launched.
