Use TOAD rebulid or perform table truncate & import?

I have 4 table(s) in a database that are showing a high number of chained rows, should I :

-open the database in mount mode, export the table(s), truncate the table &
import the data back in
or
-open the database in mount mode, use the TOAD rebuild table utility to
build the script, and run the script?

The latter seems like a lot simpler/faster process, but are there any potential pitfalls?

What is the best method to determine the optimal PCTFREE for these tables to prevent this in the future?
