When I did the 16th Edition course the lecturer said the Wiring Regulations favour cartridge fuses and they are should be the first choice for a protective device upfront of an installation.
Indeed the domestic cartridge fuse range was excellent. Nowadays they are a bit scarce to find in the local corner shop, and a bit pricey as well. People have been known to put "silver paper" around a blown cartridge fuse. I had that happen many years ago on a Christmas day when the customer's cooker became faulty and blew the 30 Amp red coloured cartridge fuse. The repair to the fuse was to cover it in tin foil and replace it. The result was a blown main 60 Amp service fuse.
Also, the 5 Amp grey coloured consumer unit cartridge fuse is a little shorter than a 5 Amp plug fuse for 13 Amp plugs, but that does not stop people trying to insert a 5 Amp plug fuse into a consumer unit cartridge fuse carrier.
Cartridge fuses are superior to wire fuses.
