I didn't come from an sp-01 so I can't compare.
I like the feel, it feels much like a tanfoglio stock 3 in the hand. While I liked how it felt, I wasn't shooting well getting used to it. I was putting in a miss per stage. Even so, it did feel good and I knew my issue was with the single action trigger being different than what I was used to (x-calibur).
A bit of practise and I think I have nailed that part down and overall I am very happy with it.
