I'd place those strings somewhere between Daddario J66 and Ernie ball Extra Slinky.
Their volume is medium.They're quieter that Daddario but definitely louder that Slinkies.Compared to Daddario I'd say they have a more mellow tone.Regarding finger noise,they are a little quieter than Daddario but nowhere near as quiet as Ernie Ball Extra Slinky,
All in all,it all comes down to what kind of sound someone prefers.
