match rtp audio vs. acl udp 16374 32767 (PQ for voice)

All,
I ran across a QoS question asking me to prioritize voice traffic on a
FR link (that was using a map-class for FRTS) and saw two ways of
doing it...

The first involves taking a MQC class-map and doing

"match protocol rtp audio"

and the second way involved creating an ACL on UDP port numbers 16374
through 32767.

Are these both correct? Is there any functional differences in the
way NBAR picks off RTP audio streams?
