Latest T05fx alternative?

Hi, with more new rubbers coming out now what are similar alternatives to Tenergy 05fx in terms of sponge hardness?

I’m not 100% sure what the actually ESN sponge hardness of T05fx is.

I have heard Nittaku fastarc C-1 and Andro Rasanter R45 are somewhat similar. If anyone has tried these or got any other suggestions it would be much appreciated.
