I doubt that there could ever be an OSC vs Mono war, since OSC would never win. It might win in a convenience war, but this is about better data and mono will always prevail.
That being said there are certain areas where the added resolution is pointless or less important, that is where OSC shines, in my opinion.
Let's compare an EdgeHD800 + ASI1600 with LRGB filters to a Orion ED80CF triplet + Nikon D610a
What's your likely goal with the edge&asi? Getting the finest possible detail out of the faint galaxies.
What's your likely goal with the ED80+Full frame DSLR? Getting super high SNR to stretch your data to reveal faint nebulosity, IFN, etc.
Would interchanging the cameras make sense? absolutely not. But there are specific uses to specific cameras. I would much rather take a full frame camera under dark skies and shoot low res high SNR widefield shots over having to mosaic my way with a Mono+LRGB.
For example, the dusty region of polaris. Virtually noone is going to zoom in to see the IFN details, right? It's about the wide field.
Compare that to the galaxy/PN setup, you will certainly zoom into the spiral arms of M81 or check out the fine detail in M82's starburst.
To me this is where you have to wager what will be better for you. What will be better for the data quality? Of course Mono. Thats why everyone who wants the best possible data WILL have to go mono. But when you don't even want high resolution, whats the point?
