Fuses always better because of high sensitivity . but Circuit breakers are more easy operation , only you have to switch on again after clearing the fault.

Fuse is better then automatic switch, because automatic switch can make malfunction but in fuse there is no chance to make mistake. Fuse is reliable then switch. If automatic switch make malfunction it will be very difficult in trouble shooting but in case of fuse you can save your time during trouble shooting .
