HEA 220: Moment of inertia 5410. Self-weight 50.5 kg/m
HEB 220: Moment of inertia 8091. Self-weight 71.5 kg/m
In other words, about 50% stronger but significantly heavier and therefore more expensive.
If the height of the beam is not an issue, you can instead choose IPE 300, which is stronger than both alternatives above, and at the same time "only" weighs 42.2 kg/m, which should be a cheaper solution.
