If you’re the kind of person who likes tinkering with hardware or software and being able to fix or upgrade stuff yourself - the OSR2+ is a great way to go. With upgraded servos, the noise is very reasonable (not to mention performance is greatly improved as well). The OSR2+ also has a ton of tuning options, including random axis movement to add flavor to single axis scripts, as well as speed and movement limiting. MFP even allows you to choose different smoothing algorithms to tune it’s behavior to suit your preferences.
If you’re more of a consumer that wants something that works out of the box and has a company that can help with repairs and tech support, go with the Handy. I had my shell crack a little bit (performance wasn’t affected at all), and decided to hit up tech support. Exchanged a few emails, and they sent a new device to me quickly. Amazing experience with them. Having opened up the device, it is pretty darn simple, and I think that the company has a good materials to profit ratio. This is good for the company’s longevity and ability to provide continued support. I always get worried when I see production stuff with seemingly small margins. Often times those companies will not be around very long. Also, A TON of us had Handys as our first devices and have had great experiences. For me, it really was the gateway toy into this whole wonderful world.
If you want something that is super quiet and don’t mind getting a product that may be in alpha/beta state, then the SSR1 could be a good option. It’s design is the newest of the 3 and is still being iterated on and improved by Tempest.
These are all my personal opinions! Sex/masturbation is such a personal activity, so don’t get too discouraged that there isn’t clear black/white guidance on what toy would be best for you.
