I guess it might come down to how much you want to spend.
Some people have upgraded from the DMK to the SkyNyx (Paul Haese is one) and swears by the move. Sean Walker has recently reviewed the DMK (Oct S&T) and (not quoting directly) says that for the price point and features, the DMK is the best planetary imager you can get.
The extra dynamic range on the Lumenera would be good, but according to Sean, only really useful on high dynamic range objects like the Sun in H-alpha. I'm sure it would also be good on parts of the moon in different light as well.
By the time you add filter wheels + RGB filters, the cost increases significantly so don't forget to add that into your equations. Those extra pieces of gear end up costing more than the camera itself in the case of the DMK - moreso if you get an automatic/motorised filter wheel as opposed to a manual one.
The other thing to consider, is that if you do have an old laptop, you may not be able to utilise the extra features (faster frames rates) of either new camera if it has trouble capturing and storing the data fast enough.
Damian Peach uses a SkyNyx, and most that have upgraded, have done so for that reason alone. Knowing the research Damian does into every aspect of his planetary imaging, there's no doubt he's weighed up the pros and cons of every imager on the market, and if he's chosen that one, there must be more than one reason why.
