I've had both the OneUp and Flexx bars. I spent a few months on the OneUp bars and about 3 weeks (so far) on the Flexx bars.
I think the OneUp bar is more to relieve minor vibration issues for people that don't have hand problems. The amount of flex is greater than what you get with a normal bar, so I think those without medical problems will feel an improvement where their hands normally start to act up, but those of us with serious issues won't get much relief. They do flex a fair bit than other bars, but for me there was no comparison, the Fasst Flexx bars had more compliance and adjustability, but it comes at a weight and price penalty. The vibrations damped by the OneUp bars are more the smaller impacts/vibrations, where the Flexx bars dull out the sharper ones much better and across a wider range.
I have no hesitation recommending the OneUp bars, but people with hand issues will get more relief from the Flexx bars.
