Currently nothing is like them because all the related species of the Elpistostegalia clade are all extinct.
As for now, the only (but very very different) animals with the ancients skills of this exinct species are:

https://en.wikipedia.org/wiki/Coelacanth

https://en.wikipedia.org/wiki/Sarcopterygii

https://en.wikipedia.org/wiki/Lungfish

https://en.wikipedia.org/wiki/Cladistia

About the caudata, all the living species are very different from the Paleozoic Amphibians.
Currently the most ancient caudata are the Cryptobranchoidea

We are probably just as "close" to Acanthostega as anything else is. As a stem 'amphibian' this taxon was close to those animals which gave rise to ALL terrestrial vertebrates - which includes lissamphibians, squamate reptiles, eusuchians, archosaurs, mammals, and turtles.
