Neither is better.  ulaw is used in T-1 land (mostly USA and Canada),
alaw is used in E-1 land (rest of the world).  It doesn't REALLY matter
which of the two you use, but there might be a tiny amount of extra
overhead if you have to convert from one to the other when hitting the
PSTN using a digital interface like PRI.
