Stray Kids debuted on March 25, 2018, and is under JYP Entertainment and Ateez debuted on October 24, 2018, under KQ Entertainment. Stray Kid's 3 Racha produces their songs while Honjoong the leader of Ateez as well as Eden and Madox which are also under KQ Entertainment produce Ateez music. They might seem similar as both groups are very performance based but Ateez is known to have a major storyline and heavy lore within each of their music videos and lyrics. Ateez is also known to put their next title track at the end of their music videos. So at the end of Deja Vu, they hinted to Atiny the snippet of their next song which was Turbulence. They do this with every music video. I think you might like some of their B-sides has their title tracks are more for intense dancing and performance.
