The cameras almost have similar specs but the C300 mark II costs twice as much!
Internationally it seems to have fallen behind the Sony FS7 though its has some advantages over the FS7
C300 mark II records 10 bit 4K in 4:2:2 at 410 Mbps per second.
The FS7 shoots 4K at 10 bit in 4:2:2 at 240 Mbps.
So C300 is better for green screen work
The C300 Mark II has extra internal ND filters.
The C300 Mark II also has an additional stop of dynamic range.
FS7 is 14 stops.
FS7 records 60 fps at 4k & 180 fps at 1080 & so does C300 mark ii but the C300 does that with a cropped sensor !
You can get superb images from both cameras, so which is best for you is basically going to come down to the needs of your production and the budget.
