TVS iQube 2.2 vs new Jupiter 110, which to buy for a person with neck and back issues?

I'm deciding between these two and would appreciate opinions from people who have actually ridden/owned either one or both.

My use case: mostly solo, Bangalore city traffic, short rides (at most 30 min), and I'm prioritizing ride comfort above everything else because of neck and back issues. I'm 5'6", ~60 kg, so comfort/ergonomics for a lighter rider are particularly important.

The confusion is mainly around the suspension/ride quality.
The iQube 2.2 doesn't have adjustable rear suspension, whereas the Jupiter 110 does, which makes me wonder whether the Jupiter would be a better choice for a lighter (~60 kg) rider. At the same time, I've read very good things about the iQube's ride quality.
I'm specifically considering the iQube 2.2, not the higher variants, because I don't want the extra weight of the higher variants to work against my neck/back comfort.

If you've ridden/owned both the iQube 2.2 and the new Jupiter 110, which would you choose specifically for ride comfort, suspension and ergonomics?

I'm not particularly concerned about range or performance. I'm mainly trying to choose the one that will be easiest on my neck/back for short city rides.

Thanks in advance!
