Damping function	Yes	No	No
Price	$2,995	$1,995	$2,495

As you can see, the Keithley 6487 is the most accurate and fastest of the three instruments. It also has a damping function that is useful for measuring capacitive devices. However, it is also the most expensive.

The Keithley 6485 is a good option if you need a high-accuracy picoammeter but don't need the fastest rise time or the damping function. It is also less expensive than the 6487.

The Agilent 34420A is a good option if you need a high-resolution picoammeter at a reasonable price. However, it is not as accurate or fast as the Keithley 6487.

Ultimately, the best instrument for you will depend on your specific needs and budget.
