The Power Of Sasuke
I will probably make a thread like this for Naruto Too...
I figured since the manga is closing to an end, it would be smart to recap and re-look the strengths and weaknesses to characters, and maybe see if Kishi screwed up at some point or not. I am also really bored and sick.. -__- So I will start with Sasuke since he is my favorite character!
Taijutsu & Reaction Time
Now Sasuke, since he was a Genin for the leaf have showed great skills in Taijutsu, only as a fresh genin he showed Taijutsu skills to that could match Kakashi's when he was a chunin. That alone is pretty remarkable, now Sasuke also posses the Sharingan which lets him copy and predict his opponent's moves by reading them. In Taijutsu, reaction time and speed plays a heavy value, and Sasuke has show incredible speed early in the series, during the Chunin Exams, getting close to matching Lee's speed. His reaction at the time wasn't all that good, but it's gotten better over the years.
Now in Shippuden Sasuke is using a sword as his primary close combat weapon, but he is still able to use normal Taijutsu. His blade skills are very good, commented by Mifune the leader of the Samurai and the best swordsman of all the Samurai. That comment from Mifune should be enough, but the fact that he is also able to infuse his Chidori into his blade makes his close combat even more deadly. Sasuke even commented that his blade isn't a blade that is easily blocked. Which is true since it cuts the edge right off Yamato's Kunai. Sasuke also combine his Sharingan with his sword making him not only able to follow his opponent's movements and block almost perfectly, but it also makes him able to target lethal places on the body much easier.
Now Sasuke's speed have been argued about, quite too much in my opinion on some sites. Well I can see why, but Sasuke has always showed great speed. Even Killer Bee is surprise when Sasuke dodge's Killer Bee's 8-Tails cloak attack. Killer Bee even says that no one besides the Raikage himself has ever been able to dodge his attack until Sasuke did it. Which probably means that Sasuke's and Raikage's ( No lighting Armor) speed/reaction are pretty much the same. Seeing as the Raikage is the 2nd fastest Shinobi that have ever lived I would say that is pretty remarkable.

Ninjutsu & Kekkai Genkai
Sasuke is a member of the Uchiha clan which made him a born Fire Style user, so he learned that pretty much from birth and at a young age he was able to master the Fireball Jutsu to prove himself to his father. He later shows that he able to use it in combat against Kakashi, he also shows that he able to do pretty strong jutsus like the "Phoenix Flower Jutsu" and "Dragon Fire Jutsu" while he is only a Genin, which is commented already by Kakashi when he sees Sasuke using the Fireball jutsu during the test.
This probably means that Sasuke has great chakra reserves and a decently strong chakra. Now Sasuke doesn't really focus to much on Fire Release later after the Chunin Exams, but that is mainly because he learns Chidori from Kakashi and he also finds out that Sasuke's born element isn't fire, but lightning. The moment Sasuke masters the Chidori before the Chunin exam he has 2 elements, which most Shinobi don't get until they are Jonin level. Sasuke is able to use the Chidori without any major risks because he has the Sharingan, which is commented by Kakashi and stated by Minato.
In Shippuden Sasuke shows that he have developed the Chidori further than Kakashi ever did, by changing its form into things like spears and onto his blade. This is something that takes a lot of practice to accomplish, since Naruto had to "cheat" with his shadow clones to do so. Now Sasuke later in the fight with Itachi, shows his most powerful jutsu which is a new form of the Kirin that uses pure lighting to no chakra is wasted. Its called the Kirin and its stated that it is the fastest jutsu that is, since it moves with the speed of lighting. The only reason that Itachi was able to survive it was the Sussanoo stated by himself.
Now after the Itachi battle, Sasuke awakens the Mangekyou Sharingan, which gives him 3 new powerful abilities. Which are the Amaterasu,Sharingan Genjutsu and Susanoo, which all have different use. Sasuke shows little skill in the Genjutsu power and he shows that he has probably the weakest Susanoo of the 3 users. But the level of which he can use the Amaterasu is remarkable! He has by far the best control over it, showing that he is able to cloak it around him like a armor and that he able to form the flames to other shapes. He has also shown that he is able to put the flames out with little problem compared to Itachi.
