    All other things being equal, the dedicated chip would be my choice.

    However, you can do 90% of what you need to for LiPo cells fairly easily anyway.

    I believe the strict requirements are:

    1) Below a certain voltage charge very slowly
    2) Charge the rest of the way with a current limited voltage source.
    3) Stop charging when the charge current falls to a certain small value.

    Really, you should never get the cells too discharged, so skip (1)

    (2) is trivial to do.

    (3) is most easily done with dedicated chips (otherwise the complexity is a lot higher)
