The disadvantages are that they are big and ugly and get very hot

Horse-puckey. They don't get any hotter than the water that's
circulated through them.


They have enclosures especially built for them which also helps
with the ugly part.

Some do. Many don't.


Another advantage is you don't need a humidifier, just put a pan of
water on top of them.
I was brought up in homes with steam radiators in NYC.

Ahh, that explains your misconceptions. You're apparently unaware
that many homes are heated by hot water, not steam.

I was raised in NYC in the 1940s. Steam was the main heating source
for many homes and buildings.
You haven't been around long enough to contradict me on what I remember.


I didn't say you remembered incorrectly -- I said you have
misconceptions about radiators. You do. They don't get any hotter than
the water that's circulated through them.

Instead of beating around the bush, steam under pressure is much hotter
than water in a hydronic system.
