While DSLRs are usually higher than 8 bit per channel, my 5DmkII is 14bit/ch, you would normally capture planetary video by capturing the zoomed liveview feed, through BYE or similar, and this would only capture 8bit/ch.
I have the QHY5L-II colour, I think this is the same chip as the ASI120MC, and it says it can capture video at 12bit/ch but I've never tried it (and I think it writes it to some weird format).
I definitely agree that there's more to image quality than resolution though and so far the best planetary stuff I've got has been using a friends Canon 7D. The combination of small pixels and sharp image seem like a good balance however I haven't had a really good go with the QHY5L-II yet.
