I've got the phantom.. personally if I could do it all over again though I'd get the tactical, shadow, or standard sp01 (shadow optimally).
I love how light the phantom is, but I really wish I could change the grips out for a standard rubber set.. which is my only real complaint about this gun. Unfortunately, the grips aren't interchangable with the polymere frames. Otherwise, it's a great choice if you are looking for a lighter handgun to haul around. Haven't been able to try out the standard version yet, but I know that the recoil isn't bad at all with the phantoms. Very comfortable and accurate to shoot.
I'm sure either way you cut it, you are going to get a nice handgun with an sp-01.. but it all comes down to personal preference. What are you planning on using it for (home-defense, range, carry)?
GL with the decision, keep us all updated.
