Well, asking this is like how you prefer to die by jumping into a well or by cutting your wrist.
The answer lies in the wave patterns of AC and DC
In AC the waveform reaches to zero in every cycle, so there is a chance that you can survive AC
On the other hand, in DC there is no such thing as frequency so there is no zero in the waveforms. So, if you get in direct contact with DC, be prepared to meet GOD

In the real world,say your talking landscape lighting, 120v landscape lights
could fail due to degradation to the wires and kill you, if you used 12v-22v DC lighting
and it fails, nothing will happen and is safer then AC.
You would die faster from your house electric then you would from a car battery.
So in the real world, DC products are safer then AC.
...assuming voltage is less. If AC voltage is less than or equal to DC, it could be a toss up. The real killer is the voltage level, and how much current backs that voltage up (ie the power that can be delivered). A taser is very high voltage, but it will not kill (or isn't supposed to) because of the very low current. There are such things as Very high voltage DC lines used to transfer power, and DC tie stations connecting the three US grids (Eastern, Western, and Texas). DC here is extremely dangerous because of the voltage level, and the massive amount of power available.
ponypomp-
Sorry,sounded kind of sarcastic. It has to do with amperage, for the most part
amps kill and not voltage. lightning, is DC,and a lot of people have lived being hit by
thousands of DC volts, people have died from 120v house current, there are so many factors with resistance and amps the explanation would fill several pages..
I added to your comment,because of the fact that for the home there are a lot of DC products VS AC products,and the dc products are a lot safer then the AC products.
I did not want people thinking they should go with AC when DC is safer, speaking
directly about home products.
Ac/dc
Ac dc
AC/DC of coarse! I don't actually know. I just like AC/DC
AC/DC, but only because there more widely known!
AC power can be transmitted more efficiently than DC.
ac
because power dissipated in ac is less than power dissipated in dc.
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
The power source is AC. Hence AC is used. DC application is limited.
ac transmission is better. because it is cheaper as converter are not use.but losses are more as comparison to dc.
dc motors generate more noise.
A rectifier converts AC voltage into DC voltage. A converter is something more general. It describes not only rectifiers, but also devices that can turn DC into AC or perform DC-to-DC or AC-to-AC conversion.
