    Better in what way? G,711 is what the telcos use for normal lines,
    and is uncompressed. Modems (internet and fax) work best through
    G.711.

    Whereas G.726 and G.729 use much less bandwidth, is a more efficient way
    of transferring the calls, and uses much more runtime encoding,
    decoding, transcoding. (whatever is happening along the route).

    G.711 will only reliably work with a modem up to around 2400bps and
    unreliably at up to 9600bps (whereas G.726/729 will not work at all).
