RNP vs Soundcraft M8 pres

[death by chandelier]

I am probably about to purchase a Soundcraft M8 mixer. I will probably have to sell my RNP to help pay for this purchase.

For those that have had experience with both of these pres, will the pres in the M8 be a step up or down (or even) from the RNP?

I like my RNP but am willing to part with it to help me get a board.

Thanks.
