Technically, lightning is the movement of electrical charges and doesn't have a temperature; however, resistance to the movement of these electrical charges causes the materials that the lightning is passing through to heat up.
If an object is a good conductor of electricity, it won't heat up as much as a poor conductor. Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).
Now the tricky part is:
1.
While Ultraguy did mention the lightsaber is hotter than the sun surface, he does not mention how much. He also mentions "it cannot cut through the hyper-dense Beskar Mandalorian metal, the hide of a Zillo Beast, or the blade of another Lightsaber".
2. If a light saber is stated elsewhere to be able to block natural lightning and Force lightning, then it simply defeats the argument for Kakashi lightning can cut through Obi-Wan's light saber and Force lightning.
3. It is important to realize that the sun's surface (or should I say, the atmosphere right above the sun surface) is actually its coolest layer. Dive a little down to its core, and you'd encounter plasma temperatures of about 15 million kelvins (about 27 million degrees Fahrenheit). Things also heat up just above the sun's surface, as its atmosphere exceeds temperatures of 500,000 kelvins (about 900,000 degrees Fahrenheit).
4.
"Power is the rate at which energy is used or transferred," explains University of Washington physics professor Robert H. Holzworth. "So power is energy per second, and the energy per second in lighting can be very high, but it only lasts a really, really, short time, like tens of microseconds. So the total energy isn't like the total energy from the sun, obviously, but the rate the energy dissipates can be very large. It's one of the most powerful natural phenomena on Earth."
So I wonder how the research crew would look into this factor. Like if the light saber is actually 500,000 kelvins instead of 10,000 kelvins this would defeat the argument of using the kakashi cutting lightning feat to dispel Obi-Wan's light saber.

I know. This is Death battle after all. At least the crew try to make up a reason for a fight. They have been accused of not giving the reason for a fight in their latest episodes, like Weiss Schnee vs Mitsuru Kirijo, Dragonzord vs Mechagodzilla and Miles Morales vs Static.
