I think i was mainly attracted to the Behringer because it had built in dsp effects while Mackie didn't offer that feature.

I used the Mackie 1202 VLZ Pro in the past and was very satisfied with it. Mackie has a better built overall, looks more solid. Behringer mixers are surprisingly light but my guess is for the price, you can't beat it.
