We had both the Keithley and the few of the HP's (although branded Keysight) where I used to work which were probably bought from an end of year surplus. When I first saw them I thought what are we ever going to use these for? However, the portable multimeters kept on disappearing while these ones stayed on the shelf so I gave them a try and I certainly found them very useful - especially the high resistance range on the HP which was very useful for finding leaking connectors.
