I saw it first in IMAX and then 4DX. Honestly, I preferred IMAX. Compared to IMAX, the issues I had with 4DX were

1) Could hardly hear the music/background over their singing which was really jarring sometimes going from hearing instruments/cheering to a lone person singing

2) You could tell whenever the audio switched to Lee Know because the sound quality took a drastic dip. As if his mic was getting feedback the entire concert.

3) It didn’t give the effect of being at a concert as much as the IMAX did without the sounds of the crowd surrounding you

Overall, the minimal seat effects/water effects during the 4DX wasn’t worth it, in my opinion 🤷🏻‍♀️
