It's the 45th sequel of the series from Super Sentai right after Kikai Sentai Zenkaiger which is the 44th sequel. If you would like to watch the super sentai series chronologically.
Kabuto's main writer Shoji Yonemura took heavy inspiration of Donbrothers' main writer Toshiki Inoue's writing style. Also Inoue is a frequent secondary writer in Kabuto. In terms of tone, atmosphere and plot progression, Kabuto is probably the closest tokusatsu to Donbrothers alongside Changéríon, despite having a darker setting.
