Hello from Tel Aviv: I would say use for products destined for Europe (rated 230 V only) use IEC 127 fuses; for products destined for North America and Japan (rated 100-125 V) use UL Listed fuses; for wide voltage range products (100-240 V for example) use UL Listed fuses. All this applies to operator-accessible fuseholders.
For internal non-accessible fuses, I would say if you wish to market products worldwide, better to use UL Listed or Recognized fuses. As you know, some Recognized fuses also have IEC 127 coverage. UL Listed fuses however, can handle 10,000A short circuit and have less of a chance to explode during an abnormal test. I never had a UL Listed or Recognized non-operator accessible fuse rejected by a European test house.
