I agree with the "pretty much always" except when you want to load balance over multiple paths. When multiple paths exist, fast switching moves data on a per-destination basis and not a per-packet basis as process switching does. Given different amounts of data will most likely be sent to different destinations, it would be possible to saturate one link while another goes relatively unused with fast switching.

[7:22262] Pretty much always, it's default, AKA fast switching. The command "no ip route-cache" enables process switching which is very CPU intensive.
