I watched Top Gun Maverick 2 years back in 1U's Screenx hall, I made a post about here but essentially imo it's bad. the screens from the left and right messes with the middle screen's image, as the light from the screens reflect off each other at the edge angle, making the image look bad. The audio too feels like it's coming from the front side only (meaning the only speakers in the hall is behind the middle screen). The worst part is that only like 2/3 of the film uses the middle screen, as I believe the side screens are only utilized during 1.9:1 scenes.

It's really a gimmick, and only works if the film is fully filmed at 1.9:1. So maybe Marvel movies (they advertised a lot for Spider-Man No Way Home at that time as the film, though IMAX exclusive for 1.9:1, utilized the side screens fully) and special ones like Avatar 2 would benefit. Otherwise, skip it and just go to the old wing of 1U for IMAX.
I mean depends on what your preference for the best screen. If image quality over anything, Onyx is the best (Tropicana Gardens and Mid Valley). If a large screen, then IMAX, particularly in Velocity or I-City. If a combination of image quality and size, BIG DA halls for imo better audio with decent image quality (particularly Starling, MyTown and Tropicana Gardens) or IMAX Laser with larger screens and better image quality.
I like this hall a lot as well, especially the hall design, dark, non-intrusive and very comfy. I also believe the speakers are stronger and clearer but that;s because they are newer compared to 1U's and Velocity's. Sure, the screen is smaller, but this is my go-to IMAX for 2.39:1 movies instead of IOI City Mall, mainly cause of the extra speakers and better ticket pricing personally.
