Depending on your requirements, and the expertise of the admins, there may be 
advantages to both.

If you have a small database (e.g. < 10 000 entries) with a low update rate 
(e.g. less than 1 modification per second), then slapadd is probably the best 

If you have a very large database, and you have frequent updates, using the 
transaction logs may provide a better means to doing a point-in-time recovery 
(especially if you need backups to be in sync with some other system).

Using an ldif dump is more portable (across different backends and database 

So, unless you have specific requirements, an LDIF export via slapcat is 
probably the best option.
