Unless you desperatly need build-in NDs, internal prores or EF lenses without an adapter.
I would have retired my 6kPro a few years ago if the FF camera had ProRes, or even a good h265 codec.
They’ve managed to put themselves in a position where their full frame 6K is significantly cheaper than their Super 35 6K version so the latter will hit that sub $1000 point when they clear it out as it makes zero sense at this point.
