I put Jones bars on my Thorn Raven Nomad and didn't like them. They're not great for multiple hand positions, drop bars are better.
I have a Jones Plus bike and the bars work better on it. It is a more upright, less aero riding position, so less weight on the hands. I still would like a neutral
hand position, equivalent to the brake hoods position on drop bars.
I personally wouldn't switch from drops to Jones, you have to take the whole geometry of the bike into account, top tube length, stem rise, etc.
I really like the Jones, taken as a whole. I like my drop bar bike as well, they are just different beasts.
