Neither. If budget is a concern and you want maximum function, AUX send/returns, and an output, check out Ladik's M-175 mixer and M-053 AUX Mixer. With these, you get it all in 20 hp, for $147-ish + shipping. This gives you three mono AUX sends, four pannable mono mixer channels, plus two more stereo mixer channels suitable for AUX returns. And the mixer has dual 1/4" TRS outputs with a master level control. For this sort of thing on a budget, it doesn't get much better.
