no difference. GSC MAXX have ONE hall only, just u see the MAXX1 is actually separate section only in the SYSTEM of the seating number and booking.
the MAXX1 actually for the peeps who buy at the ticket counter and not by online booking at first.

But they opened it when the system detect on the MAXX nearly fully book by online and automatically opens MAXX1 for online booking that supposedly open for the people who buying @ the counter.

I dunno much, my friends who working @ there told me this.

yeap, agree with u, there A LOT of difference when watching in MAXX.

Oh and one more thing, please make sure/double confirm ur glasses is fully working and in fully charge state before the movie starts.
This can be done when u wearing the glasses and watching the trailers that shows in 3d.
If u experience like slowing flicker thingy on ur glasses /something that u heard like a bit camera shutter sound repeatedly , that shows the sign for the battery is out of power.
When this happen, immediately change the glasses to nearest gsc worker. or go to area that lend u the glasses before u entering the hall.

This happen with me when watching TF3 for the 2nd time this week
