For my part, no, I've always replaced them (where doable) with the common IEC C14 chassis inlets. See the bottom of my web page. Yes it does require some cutting of the original, so it depends on whether one wants to do that, and one's will and skill with hand files.

I've never tried the C6 type as I rarely see them anyways. Note the C5/C6 has a considerably lower current rating than the C13/C14, which is presumably why it was introduced as an additional standard.

I keep around a box of C14s scavenged from discarded equipment for the purpose, but I also replace fixed lines cords with C14s whenever I can, because I hate moving and storing equipment with dangling power cords.
