Tantalum was used in the phone industry for many years.
It was the best choice in terms of capacity/volume ratio.
Tantalum ESR was and still is pretty high: 100 mOhm to 1 Ohm on the average.
There was a huge shortage of tantalum in 2000/2001 all over the world. Prices raiesed upincreased a lot.
Murata has been steadily working on improving the capacity/volume ratio of their ceramic capacitors and made huge steps ahead.
At the moment, the ESR of ceramic capacitors is much better than Tantalum.
To answer your question: I don't see any electrical advantage of tantalum capacitors.
I quit using them back in 2001.
