two things to note:

1. PCM is uncompressed and AC3 is compressed. Hence PCM preserve the original quality of the audio more than AC3.

2. PCM support/carry 2 channels, while AC3 can carry 6 channels. So, AC3 is best suited than PCM while using 5.1 systems or higher

you can decide based on this.... tup:tup
