It depends what you need.  If you need command-line argument 
compatibility with some other hosts, then gtar is better since it will 
install pretty much everywhere (and is the default on e.g. Linux).  Or 
if gtar does something that BSD tar doesn't (incremental "backups", 
maybe?  who knows what other bloat).  Otherwise, I have never found any 
specific disadvantage to BSD tar.  You can easily have both and the 
actual tar files should be compatible.
