NG only has about 30-40% of the energy, per cubic foot of gas, of propane though. so if the price was 60-70% less, it would really be on par.
propane is compressible into liquid though, so you can fit more of it in a smaller space, which is why it is popular in portable tanks.
NG is also a greenhouse gas (if it is released without burning). propane is not classified as harmful to the environment.
