I use a continuity to get a yes/no answer to whether two things are connected, so I don't need adjustable voltage, threshold, etc.
I do like the latching beeper and fast reaction of both of my Flukes, my 179 and 16. I also like the fact that they use low enough voltage so as not to send semiconductor junctions into conduction, so they don't indicate continuity through diodes and transistors.
I like the V-Check feature of my Fluke 16. If I accidentally connect it to a voltage source of more than 4.5V (AC or DC), it will switch to voltage measurement mode and display the voltage. Without causing any damage whatsoever to the meter.
