Radiant Heat Hot Water Systems

What is the best type of heating system for a house?
I am talking about hot air systems, radiant systems, hot water/steam systems. If someone knows about a system I have not heard of before,(did not list) please tell me about it too.
Thank You. Your aid will be greatly appreciated
This was a question asked by my Science teacher.
As you probably know it is part of a good design to optimize for the constrains defining the problem. Every system while has advantages over the other has its own flaws.
Here is the table
a- forced air
b. Floor radiant
c. Register radiant water
d. Register radiant steam
_______________
Easy to implement (2, 2, 4, 4)
Easy to change/move (2, 1, 1, 5)
Dry air (4, 3, 3, 1)
Dual function AC and Heating (1, 2, 3, x)
Leaking requires attention (1, 5, 5, 6)
Heating speed (1, 2, 3, 3)
Sharp on /off curve (4, 2, 2, 3)

Forced air systems are great for fast heating and great for both cooling and heating the space.
