I've continually drank coffee for most of my professional career, ranging from 2 to 6 cups a day. Given it up a few times cold-turkey resulting in annoying withdrawal symptoms mostly headaches and fuzziness.

After a week or two notice an overall increase in energy and no crash/down hours at the end of the workday.

The downside to being off caffeine is heightened awareness of everything around me. This is great if I'm on vacation smelling the flowers but terrible for trying to focus on software development ignoring disturbances and self-induced distractions. The closest I've found to a good balance is about 2 cups only on weekdays, but with lockdowns weekday and weekend habits have merged into a blur.
