imax for picture and sound (has a higher resolution projector 44 speaker surround sound to ensure complete surround for everyone)
in terms of movies it will only look better in Imax is the film was shot using Imax cameras otherwise the picturer is just upscaled like Fast5 or it may not even be upscaled hence why it may seem like you get sharper images in ultraavx
also depends if the projectionist has the image @ optimal brightness when it comes to 3D movies (they usually dont though)
ultraavx for being able to reserve seats (5.1 or 7.1 if the theatre is equipped with it or 11.1 when available)
