Well, for one, you never asked me to elaborate, probably because you were too busy throwing around baseless accusations like this one
But if you're curious, I don't find the bigger screen to be any more immersive--in fact, I find it to be a hindrance--I don't like how close-up I am to the action, especially with how the range of what I'd consider to be a seat with a decent, non-distorted view seems greatly reduced. Furthermore, I've found the actual seats at the Dolby theaters I've been to be much more comfortable than IMAX's offerings, and I would probably opt for the comfortable seating regardless, even if I preferred how IMAX looks.
