IMAX is a special format. It is a very big screen, about 7 stories tall, and very wide. It has speakers placed all behind the screen as well as the sides and back. If you're in a theatre with Dolby Atmos, it has speakers on the ceiling too. The seating is arranged like a stadium, so its impossible to have your view blocked. The image is rock-steady. If you're in a Digital IMAX theatre, the picture is even better as it has no film-noise (dust, scratches etc) of regular film.
IMAX 3D is different from normal 3D. Normal 3D uses cheaper polarized glasses to view 3D. IMAX 3D uses shutter glasses. Essentially, the are lens that open and close very rapidly so that each eye sees only 1 image at a time. The glasses have a battery to power the LCD shutters, and a sensor to keep it in sync with the projected image. It's flawless and seamless and provides the best 3D you can see in the movies. The quality of the 3D effect is limited by the quality of the 3D process used in making the movie. The gold standard is the movie Avatar because it was shot with 2 cameras (1 for the left eye and the other for the right eye). Most other movies including Star Wars however are shot with a single camera. The movie is then processed afterwards and the 3D effect added with CG and or extrapolated from 2D objects or markers from the original film. I don't know why this seems to be the preferred method. I'm guessing it's cheaper and gives the director more control in post but I'm just guessing.
