What is the difference? Besides customer preference, why does the 752 have either a 4 or 5 door option, but the 753 only have the 6 door option? Why does the 763 come with 3+1 or 2+2 exits? Why doesnt the 764 have options? Why do none of the 777s have door options? What's the purpose?

The 757-200 comes with 2 major fuselage options (3 if you count freighter, 4 if you count the unique combi version made for Nepal), Overwing exit or 4-door. The overwing exit configuration has 4 overwing exit 'hatches' plus 6 full size access doors. The 4-door version has 6 full size doors and 2 emergency doors located just behind the wing. This change in configuration is used to accomodate lav/galley configurations for each airline.
When they were certifying the 757-300, the number and type of exits for the overwing or 4-door configuration were not sufficient to comply with the FAR's (25.807 and 25.809). To overcome this, Boeing just combined the two configurations for the 757-300. therefore all 757-300s come with 2 overwing exits and 8 doors (6 full size access doors and 2 emergency door just aft of the wing).

(In general) I think the 8 door 757 is used by carriers who want to fly longer distances. In this mode the rear bathrooms are at the 3rd door, instead of next to the galley, which is much more convient for the pax and f/a.
