Mono is best because of how the sensors recieve an image. With a colored sensor its takes 4 pixels to show a color pixel, 2 green 1 red and 1 blue. With a mono you use only 1 pixel and colours are made by using filters so you get a much higher definition image. The problem with mono's are you need a set of filters and a wheel/side, also with planets that spin fast you have to be quick to switch filters and can't gather the same number of frames as a color so you have less to stack. Colored ccd's have a huge advantage for planetary imaging because they can gather more frames in the same time but lose out in resolution to the mono's.
If planets are your target your best with a colored ccd with the fastest FPS you can get, highest res and a loseless codec. This will give you the best chance of getting good frames to stack and produce a nice colored image. Theres nothing wrong with mono's apart from the time you have and chance of getting good frames due to atmospheric change.
For DSO's, nebula ect is your target then go a mono though sooner or later you will probably want a higher res camera and at that stage and price bracket it may be a toss up of colored ccd/mono/dslr pending on your budget, skill and targets ect.
