Difference in video quality

I have 2 mkv files of the same movie, both 1920x1080.
The specs of the first are:
Bit depth: 10 bits
BitRate:14.7Mbps
Format Profile: High 10@L5.1
11 RefFrames

The specs of the second:
Bit Depth: 8bits
BitRate:14Mbps
Format Profile: High@L4.1
4 RefFrames

Which one you think has the best quality?
Thanks!
