The 13 amp fuse with blow at the lower rate to the 15 amp fuse.
And
At 15 amp the motor is normally more powerful - check the wattage used in both
Tough to tell. The extra amps may buy you some extra torque, but will cost you more to run. You are better off trying to read some reviews on-line since there are many other factors to consider.
The difference between fuses is the current that they are designed to support. A fuse is intended as a safety measure to protect against overload. A 3 amp fuse should burn out if more than 3 amps is run through it, with some allowance for standard variance. A 13 amp fuse would burn out with greater than 13 amps. It is always a bad idea to use a fuse bigger than you need, because if your component is designed for a 3 amp fuse and you use a 13 amp fuse, there is a good chance you could damage your component with too much amperage because the fuse would not burn out at 3 amps, as was intended.
The difference between 13 and 16 is 3. To find the difference between two numbers subtract the larger number by the smaller number. (16-13=3)

Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown).
Both are 13.

The difference between 13 and 5 is 8. 13 - 5 = 8 (check sum is 8 + 5 = 13)
The difference is 43o F
