Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_203_356 ( id number, "type" text, "diagonal (mm)" text, "width (mm)" text, "height (mm)" text, "area (mm2)" text, "stops (area)" number, "crop factor" text )

### Question ###
which has a larger diagonal : super 8mm film or imax ?

### Accurate SQL ###

SELECT "type" FROM table_203_356 WHERE "type" IN ('super 8mm film frame', 'imax film frame') ORDER BY "diagonal (mm)" DESC LIMIT 1
