I’ve had multiple S2s (with and without optics cuts), CZ75 variants and now 2 Bull Shadow variants.
personally, the standard Bull shadow is a perfect blend of S2 and SP01. I like the short dust cover and rounded trigger guard. It’s more balanced toward the rear (and adding heavier grips and extra cap Mag further pulls the balance into the palm).
but in reality, only you can decide which suits your hand and shooting style best.
