Which is better high input impedance or low input impedance and why?

That depends on the output impedance.
In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.
An input impedance is called also a load impedance or an external impedance.
An output impedance is called also a source impedance or an internal impedance.

Compared to bipolars FETs have-a high input impedance b low input impedance c same input impedance?
FET s have very high input impedance when compared with Bipolar transistors.
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
Why is output impedance kept low?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Input impedance is greater than to load impedance?
In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high

Why output impedence is high in opamp?
Output impedance in an op-amp is not high - it is low - input impendance is high, and this is because the input stage transistors have high gain.
Why input impedance of any amplifier should very high?
