I have an old ZM-11(U) LCR Bridge and think the "Old School" High Voltage insulation test are the only one that matter when it comes to checking high voltage capacitors. Also, you can see the reforming of high voltage electrolytics in real time. Not uncommon to find old capacitors that have been on the shelf for decades start out leaky and over time see the leakage drop under test.
Have a huge General Radio 650 that I use for low value resistances and also checking impedance of things like audio transformers and am a big believer in bridge technology but beyond that don't have a lot of faith little digital LCR and ESR test gadgets.
