I totally know how you feel =w=
I bought a Dual Shock 3 and DMC4 before getting a PS3 X3
(Back then, PS3 were packaged with the non-vibrating Six-Axis, so the Dual Shock 3 has to be bought separately).
I remember doing "image training" by playing the Credo boss battle on YouTube and clicking away at my unpacked Dual Shock 3.
Funny enough I also bought a Duel Shock 5 (I like having a second controller on charge for when the one I'm using dies and needs charging).
Actually sat back and pretended I was performing stinger and high time. Followed by fireing off some shots from Ebony & Ivory, then a helm breaker.
Side note, now that I've held one in my hands I think the DS5 feels very comfortable. I wasn't fond of the DS4 at first, they just felt kinda weird. The DS5? I'm already liking it
