Energy Ball's base power is a constant 80. What is Grass Knot's base average power?
Taking into account May's statistics and type coverage, Grass Knot's average base power is 79.9.
I decided to also calculate what would be Low Kick's average base power. It is actually even higher: 80.8. Unfortunately, most Pokemon that learn Low Kick also learn a Fighting move of higher base power.
So basically, on average, both deal practically the same amount of damage.
