In terms of combat skills, Jango has the upper hand. He has undergone rigorous training under bounty hunters like Hondo Ohnaka, Duros Cad Bane, Aurra Sing, and Zam Wesell. Boba may seem cooler in fighting, but his father is more skillful than him in hand-to-hand combat.
Known as the best bounty hunter in the galaxy during the final years of the Galactic Republic, Fett was proficient in marksmanship as well as unarmed combat. The Mandalorian armor that he wore featured various weapons and gadgets, including a flamethrower, dual WESTAR-34 blaster pistols, and a jetpack.
Jango Fett, but not by a lot. The guy managed to go toe-to-toe against one of the most powerful Jedi of all time (Obi-Wan). He was also hand-picked for cloning to create the most powerful army in the Galaxy.
While Jango Fett was a skilled fighter, his abandonment of "The Way" and his reliance on gadgets and tricks instead of discipline may have contributed to his swift defeat by Mace Windu.
From Jango Fett doing everything Boba Fett didn't do - fought Jedi, worked more closely with the Sith, made a more widespread impact on the Star Wars universe - to the introduction of this new weapon that blows anything Boba used out of the water, it's more than fair to say that Jango Fett is Star Wars' coolest bounty ...
In terms of combat skills, Jango has the upper hand. He has undergone rigorous training under bounty hunters like Hondo Ohnaka, Duros Cad Bane, Aurra Sing, and Zam Wesell. Boba may seem cooler in fighting, but his father is more skillful than him in hand-to-hand combat.
It was then that Fett would carry out the act that would make him both famous and infamous for the rest of his life and career: using no weapon beyond his own hands, feet, and armored body, Fett vengefully killed six Jedi, including the one killed Myles.
Jango hated the Jedi for what they took from him. Perhaps he even hated him for having a home to return to after helping the New Mandalorians take his. Whatever the reason, he hated the Jedi enough to become essential to Palpatine's elaborate plans of genocide.
In his time as a Bounty Hunter, Jango is only known to have killed one Jedi, Coleman Trebor. However, he did kill six Jedi with his bare hands during the Battle of Galidraan, when he was still a soldier.
Boba Fett's Arrogance Makes Him Susceptible to Attacks
This leads to him unexpectedly being taken down by one ridiculous swing. This is shocking because it shows that underneath Boba's cool demeanor, his obsessive arrogance is a huge flaw that makes him terrible at his job.
There's no doubt that Shae Vizla is one of the strongest and most feared Mandalorian warriors in Star Wars history, as she was feared by Jedi and Sith alike during the age of the Old Republic.
Mando would be smart enough to use this guy when Boba can't get away, or possibly deflect it with one of his lightsabers! So in the end, While Boba Fett had the more destructive arsenal, and had more experienced, Mando just had the better armour armour, the skill, and the versatility to take Down Boba Fett.
Boba Fett is shown to have accumulated a sizable collection of lightsabers from Jedi he defeated and he is explicitly shown to have defeated and captured Jedi Knight Rachi Sitra in the Galactic Hunters expansion of the Star Wars Galaxies Trading Card Game.
While seemingly killed in Return of the Jedi after falling into a sarlacc, he has since appeared in Star Wars media set after the film, confirming his survival within the new canon, portrayed by Temuera Morrison.
He is primarily motivated by profit and usually only loyal to the highest bidder. Fett always focuses on maintaining peak condition with his body, mind, and equipment.
Both are excellent bounty hunters, and both have held the title of “greatest bounty hunter in the galaxy”. The difference is, Jango got this title from being a huge badass and earning the title. While Cad Bane is also a huge badass and a great hunter, he got the title after Jango's death, not from surpassing him.
In the Star Wars Legends, Jango Fett was a legitimate Mandalorian. Much of Jango and Boba's past has been mysterious, with many speculating that Jango stole the Mandalorian armour or even that it was gifted to him by real Mandalorians.
In The Clone Wars, Boba Fett was near obsessed with the prospect of killing Mace Windu, and didn't seem to care much at also having the opportunity to kill Anakin Skywalker when the opportunity came up, focusing solely on Windu.
He powerful both physically and mentally, didn't care much for the Republic and was Palpatine's preferred species. So, in a move that could've risked his entire plan, Palpatine sent Count Dooku to Jango to make him an offer -- a hefty 20 million credits to make him the Clone template.
The last great struggle between the Jedi and the Mandalorian warlords resulted in a large battle on Mandalore. This caused a cataclysm that scorched much of the planet's surface into lifeless white desert and ending the conflict, the Jedi emerging victorious.
In the Star Wars prequels, Jango removes his helmet more or less whenever he's not fighting, happy for Obi-Wan, the people of Kamino, Count Dooku and others to see his (or, indeed, Temuera Morrison's) face.
