The main difference that I see between the PLB's and an EPIRB is who do they alert if you push the SOS button. The PLB's as far as I can see alert the service group that they are associated with and then they have to alert the proper authorities. The EPIRB goes directly to the proper authorities and also as has been mentioned gives assistance directly to them if they are trying to reach you. I'd want the second scenario if in dire need of help.
An analogy would be that you subscribe to a home security service. You think someone is in the house that shouldn't be there. Do you want to contact the security service and then rely on them to call the police and send them or do you want to just dial 911.
For the Gulf Stream crossing part of the trip chances are the Coast Guard could get to you fairly quickly regardless of if you used any of these devices or just used the 'distress' button on your VHF radio. Once you are over by the Exumas who is going to come to you if you need help. Basically no one. I think the Bahama navy or whatever it is call has only a couple boats, but I did see the same one twice in the Exumas so that is encouraging,

P.S. No Bahama pictures or trip report as we are headed back to the yard with our current transmission problems
