SNAT vs Auto-map

To me, the biggies are (in favor of specific SNAT vs. Automap):

 

 

1) You can be much more flexible regarding ephemeral port exhaustion.

 

2) It helps reduce confusion when you're troubleshooting.

 

3) You can tune the timeout values on a snat pool, unlike automap.

 

 

Also, CMP can complicate the ephemeral port exhaustion issues, and some folks out there consider it to be best practice to setup a 1:1 mapping between the Virtual Server and a dedicated SNAT pool.
