IMAX or 4K?

As the days near the release of TLK 3D at the theaters, I'm having a hard time deciding whether or not to go see TLK on IMAX or regular 4K screen. I was thinking on going to see it on IMAX, but now I'm not so sure. Is IMAX the same quality 4K?? Doesn't IMAX use film instead of digital projectors?
What will bring the best TLK experience? I need help deciding!
And also, I guess I can turn this topic like the "Are YOU going to see TLK in 3D?" and ask, "Are YOU going to see TLK in IMAX?"
That way it'll help me decide!
Thanks!
