Helix Syn Trident vs Helix Trident

Should I go for Helix Syn Trident (the black one with two dots), Helix Trident (the white one), or a different model? Also I noticed the price difference on the official website, but in my local sex shop, the more expensive Syn Trident is cheaper. It would be my first “real” prostate toy, the previous one is a weakly vibrating plug, which does not do much for me, and I’m not sure I want to spend my time learning to use it, I’d rather use something good from the start. Also, I was thinking about njoy pure wand, or multiple vibrating massagers, but currently I would like something normal sized, and not over complicated, like the Aneros brand.
Thanks for you help!
