The kernel mode PPP should conceptually be more efficient and robust because
it is built into the kernel. It does not have the same problems of context
switching, using memory per process, etc. etc...
However, the user mode PPP is easier to debug and hack on. It has some
rather severe bugs for any site that wants to run more than just a few, but
these are known quantities and tend to be easier to fix than kernel bugs. :-)
