There is no comparison between the two mixers. The Sound Devices 442 wins hands down.
I have used both mixers extensively, and the Sound Devices is better in every category. It sounds better, the meters are better, it is much more durable, and Sound Devices customer service cannot be beat. Trust me, don't waste your time with the PSC, it may be cheaper, but in this case you certainly get what you pay for.
I'm a very happy Sound Devices 442 owner!
