The 294m is a bit more versatile in that it can be 47mp or 11mp.
The 47mp would suit the ED80 and the 11mp would suit the Meade 8 inch SCT.
But it requires filters, filter wheel.
Colour cameras are these days very sensitive and have good Ha response for nebulas. Their images are easier to process.
The downside is whilst they are a lot more sensitive to narrowband than they used to be they are not ideal if you want to be imaging narrowband to get over light pollution.
