DDJ-400 recording quality compared to other pioneer devices

Hey

I'm about to record my first set

I have the DDJ-400 unit

I would really like the sound quality to be as good as possible.

My friend owns a nxs2 and I wondered if the recording quality is better on his unit so I would record my set on it, or if its the same so ill not bother him and use my ddj-400.

Any tips of recording on the highest quality would be awesome.

Thanks.
