the different Sannomiya stations

There are about 4 or 5 lines stopping at Sannomiya. Are the station names different for JR, Hanshin, Hankyu and subway? From Osaka to Kobe, JR is supposed to be faster but when I check the route in Hyperdia, it is confusing for me (too many transfers). Perhaps I'm putting in the wrong station name and JR station in Sannomiya has a different name?
Thank you.

The station names are different, but it's easy to choose in Hyperdia. For example, JR Sannomiya station is listed as Sannomiya(JR) while Hanshin is listed as Sannomiya(Hanshin), etc.

JR is faster, but it depends on the departure time and overall you're talking about a few minutes here and there. More info here:

thanks yllwsmrf, there is another station called "Kobe Sannomiya". Is this another railway?

Yes, that's Hankyu's Sannomiya Station. But I wouldn't worry about it to much. They're essentially all connected.
