Not a fair comparison. Old steel boats are invariably "cheap" - reflecting how people value them. If they suit your needs are you are happy with dealing with the downsides then clearly they are better value for you than an IP. However, not everybody values the same things, hence the availability of boats in all kinds of size, type and price range.
A steel boat would be much safer in a collision with a cargo container in the night,or an uncharted reef. Ips have such narrow side decks that getting forward in a hurry can be a challenge, and risky.
Excessive beam means a low AVS angle, and doubtful self righting ability in a rollover.
I prefer boats designed by someone with some actual offshore cruising experience, not an armchair expert, who has never been to sea for any long term cruising ( which shows up in poor detail design). For some designers, people just "Assume" they have offshore cruising experience, when, in reality, they have none.
A friend used to buy and sell old boats for a living. If one had no interest, he would double the price, and it would then sell quickly, as people judged the value and "Quality" of the boat by the price tag he put on it. Seems to work for boats like the IP, and others.
