Aneros Vice 2 vs Helix Syn V while sitting down.

I’ve been toying with anal toys for almost 7 years, but only truly delved for past 3 years or so. All these time, I thought
1. Vibrating is better than manual
2. Girth is better the bigger
for the longest time – up until I tried Aneros Helix Syn Trident, and experienced a true Super O. Previously, regular penis masturbation with anal toy was only way to achieve orgasm. I thought Super O and other hands-free orgasm were purely mental, and thus out of my reach. I was beyond happy.

However, now that I know what my prostate likes, I’m split/confused as to what to buy: Aneros Vice 2 vs Helix Syn V, especially while sitting down. I now know that size isn’t important to my Super O, and have been enjoying lack of residual pain at my anus after insertion and play. And I’ve been told that stronger vibration doesn’t necessarily make anal play happy for long, as they get numb.

If I’m not married to size nor greater vibration, should I get Helix Syn V or Vice 2? Does stronger vibration and remote make critical difference in solo play? Or am I asking a wrong question?

Thank you in advance.
