Tethering vs Mobile Hotspot

I went through the few discussions on the forum regarding Bridge vs. Tethering vs. Mobile Hotspot.
I understand the speed differences and the ability of applications to connect (or not) to the internet based on the connection.
In my case Tethering & Mobile Hotspot both included in my AT&T Data Share Plan. My question is: beside the fact that Mobile Hotspot will devour my battery, is there any advantage to use tethering instead of Mobile Hotspot?

Can�t wait to get my PB 64 GB next week �
