Which audio track is best (DD or PCM) on Rocky Balboa?

[wesg92]

I haven't seen a PCM audio track before and wondering which one is best to select.

Track #1 is AC-3 Dolby Digital, but is "Lossy", 640 kb/s bit rate.

Track #2 is PCM, 4 608 kb/s bit rate.

Thanks!

PCM is essentially uncompressed audio. Blu-ray.com says Rocky Balboa (2006) has a LPCM 5.1 audio track. That's the 'highest quality' track on the disc.
