If you think about the physics involved, if you hit something the energy involved has to go somewhere. With a lead keel much of it goes into deformation which is a pretty easy fix. With an iron keel, most of the energy gets carried upward into the hull and is a good opportunity to test the integrity of the keel/hull joint.

Iron keels came into use because they were cheaper and this became even more of an issue as lead prices soared. Some builders offer lead as an extra-price option and it is significant. To me it would not be a deal breaker, but I would certainly prefer lead.
Heading back to Lake Ontario for this summer. Now in Bermuda and heading to Long Island Sound in the first week in May. Then on to the Hudson and the Erie Canal.

In a cruiser; does it matter that much?
No and that's why now on almost all modern mass production boats the bulbs are in iron. It only maters to someone that wants to maximize performance and only performance boats offer that, many times as an option. But I am only talking about the keels that now are the norm in Europe. On all cast (iron or lead) the difference can be considerable between the two, in drag and weight that also affects performance.
