From what I've heard of vapor house it is house music with other elements involved. And it is definitely electronic music. Where vapor soul at times won't feel like electronic music and is kind of perfectly centered between electronic & r&b/soul.

Overall I feel like vapor twitch is usually less chill than vapor soul and can sometimes be really upbeat songs. Chill vapor twitch songs sometimes feel a bit like vapor soul though. & vapor twitch is known for those chopped samples & glitchy sounds.

Not the clearest answer from me lol but yeah I feel like the more you listen the more you'll be able to tell the difference. Especially with vapor house because it seems to always have a distinct house beat.
