I snip the caps with some small and very sharp hobby side cutters right above the bottom ring at the base of the cap. What's left is the bottom ring that lifts off and leaves just the leg stub and pad which I de-solder after cleaning the PCB and electrolytic shit that leaked out Takes 2 or 3 snips and it's very quick and safe. I haven't lifted a single pad since I started doing it like this and can de-cap a board very quickly.
