Of the ones you mentioned, I've tried the Gold Laced G (which I love), the Swirly Deuce (which doesn't fit me and I'm heartbroken). I've got the Bumpy Spiral Double Dong which is very similar on one end to the Pink Swirl G (and that's great for rocked G-spotting with some nice texture---but I like the bumped end better than the swirled end).
So, rocking? Thrusting? If thrusting, definitely choose the Gold Laced G.
Also, for the swirly deuce, measure your body first and then check out my comparison video for the sizes. (over
here).
