expdp is Export Data Pump

exp is just export - which is the older version, included for backward compatibility.

Expdp is usually preferred - it's generally faster.

See the docs: http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_export.htm#SUTIL200

I typically use the classic exp.  You can run this from a remote client and have the file saved on that remote client.

The datapump version places the file on the database server.

True - for data pump you do need to create a "directory" inside the instance so that Oracle can write to the server file system and grant permissions on that directory to the user who is doing the export.

Also, on the import side, impdp doesn't seem to handle referential integrity constraints very well - where as imp seems like it will load all the data and then enable constraints at the end.

However, impdp gives you great flexibility in remapping users and tablespaces on the import that imp does not.

I guess you need to find out what your requirements are and use what suits your individual requirements best.

I've found that Datapump is generally faster, but from time to time there are still databases I have where I use import / export.

As in many database related questions, there are not necessarily absolute answers.  The answer is often "it depends" :)

I will prefer and we are using the expdp for schema / table / full export, which is fastest and convenient when compared to exp.

Your closing comment mentioned datapump worked but you selected an answer that didn't suggest using it.
