At the battle of Hoth with only two rebel soldiers, they were able to kill at least 100 snow troopers from preventing them from reaching Echo base, reach 3 turret stations and destroy at least 10 AT-STs on his own, survive a battle against his brother, now an amateur sith, and do most of the work in destroying the star destroyer Avarice. Sure he had Shara, but she was nowhere near his level as a soldier. He was able to take down many imperials at the battle of Yavin 4 including finding a transponder from the death star. He also with master Kota's assistance was able to rescue 5 rebel soldier in a mission that may have taken hundreds of regular rebel soldiers to accomplish. After the rebellion had formed, X2 was able to defeat quite a few imperials at a battle to slow the empire's progress on building the death star. Obi-wan barely escaped Utapua after order 66 was executed which was impressive. If there wasn't a gun in sight, General grievous would have killed Obi-wan. Without Anakin, Obi-wan would have been killed by count Dooku. However, if it wasn't for X2, he wouldn't have gotten to Grievous' flagship.

While for Obi-wan help lead clones in several victories, his most notable were at Coruscant at Grievous' flagship and at Utapua. While X2 killed master Ferroda, it was probably better for X2 since he now knew the republic is evil. #3 X2 was able to survive a battle against general grievous as a soldier, assist in getting Anakin and Obi-wan aboard Grievous' flagship, take control of a separatist frigate with only 2 clones, and basically do all the work on Cato Neimado as a soldier before order 66 was executed a. X2 because he can do small earthquakes makes him superior. They both may have other abilities, but they have not been seen at least to my knowledge. Obi-wan can throw objects also, jedi mind trick, throw his lightsaber. X2 has been able to throw objects, throw his lightsaber, use jedi mind tricks, and can make a small earthquake nearby to knock nearby enemies off balance. #1 Both are very skilled in lightsaber duels so they are even there. Here is what I consider the aspects that either make or do not make a jedi.

Now let's see what happens when we compare them since Obi-wan is one of the best jedi.

It doesn't matter if Obi-wan Kenobi is the best, this debate is if X2 is either one of, or the greatest Jedi.
