Yeah, it's the peak of samurai combat and romanticism, mostly due to the 200 years of peace that followed, giving those war-deprived samurai centuries to build up the legends of their forebearers
Unlike how CK3's time period is mostly just court scheming in Kansai between the Fujiwara and Tachibana until the Taira and Minamoto come to blows, Sengoku was ~150 year FFA from Kyushu to Aomori, with hundreds of warlords/clans rising and falling, but making impacts on their local history. These characters and their snippets of personality creates a bunch of larger than life characters and conflicts, such as Takeda-Uesugi wars, the Ouchi attempts of playing Shogun-maker, the arrival of the Jesuits and introduction of matchlocks, the Ikko-Ikki and growth of the ashigaru, the rise of the Oda clan, the assassination of Nobunaga after his near-unification, Hideyoshi's assumption of power and the invasion of Korea, the execution of Sen no Rikyū, Nobunaga triumphant at Sekigahara, and the last gasp at the siege of Osaka.
Asian recordkeeping is great and they have the care to deeply cherish some of their regional champions.
