Digital 3D is better than IMAX. IMAX screens are mostly analog, huge but are blurry and use linear polarization. Digital 3D use circular polarization so you don't have to stick motionless with your seat. More, its not going to get you any headaches. IMAX screens use 70 mm film for better resolution but that is all. The future is of Digital 3D because of ease of use and nominal price in comparison to IMAX.
