Either should tell you the frequency and timing response of your
room, after doing reverberation and absorption tests with various
test signals (including sine wave sweeps). The absorption tests
should tell you that, if a frequency range gets absorbed more than
other ranges, you'll need to amplify that range with your equalizer.
As far as reverberation, placement of speakers might help, but I
think this is more a function of the shape and materials of your room.
