Is XM Weather Worth It VS Adsb in?

Thanks mshac, I've read the article and a few others (most through Sporty's iPad News), but I would like to see if XM has Gulf of Mexico specific satellite products like FF has. Of course, once out in the Gulf XM would provide the radar images along the coast, what I'm facing on the way back onshore.

I'm lucky with the ADS-B. There is an antenna overlooking my hangar ramp. I have everything on the ground before departure.
