It depends on what you want to measure and how much work you want to do, you mentioned neither in your enquiry.
All meters are ammeters (it's the current in the coil that causes meter deflection).
The voltmeter will already have a series resistor built into it such that it takes 5 volts to cause full scale deflection.
The 1mA ammeter is the best option if you want to measure current flow as its self-resistance will be relatively low and hence have minimal effect on circuit current flow.
If you wish to measure more than 1mA using the current meter you will need a suitable shunt resistor and if you wish to measure voltage using the same meter you will need a suitable series resistor.
