Hi,
I love the CO option to see the focus check with the contrast mask.
This will be very handy when shooting tethered with a manual focus camera system.
The layout of CO is somewhat nicer and there are a lot of options more than in LC.
The main thing about CO is that renaming is much easier for batch and there are a lot of options that LC is lacking.
CO is more of a complete solution in my opinion whilst LC is a rock solid and fast tethered solution.
I'm switching to CO from LC.
