Donic Acuda S2 and Donic Bluestorm Z3

[pendulumboi]

Is there a huge difference between this two rubbers? Im currently using Acuda S2 for my backhand and i love it, the dwell time is just awesome, flicks and power shots. But i wanna see if Bluestorm Z3 can be as close as my acuda s2. because i saw that they both have 42.5 degrees of hardness. I remember 2 years ago i used the Z1 version for my backhand but cannot remember how good i played with it... so i need suggestions
