When I tried the Hanson, I liked the fact that the register key was closer to the thumbhole than on many other clarinets and that made it much easier to play the throat Bb than on the clarinet I had at the time. I think the A key was also in a better position as well, but it's a while since I tried it and I can't quite remember. This may not mean anything to you if you're not familiar with clarinets, but if you have a look at a few in the shops, have a close look at the different spacings of the register key at the back and the A key at the front. And although the difference might appear miniscule, it can make a big difference as to how easy it is to play. Anyway, back to Hanson - I'm pretty certain they'll send one out on trial (I think you pay in advance and then get a refund if you don't want to keep it).
Personally I think the position of the thumbrest makes a big difference to how easy it is to play - the thumbrest on my old clarinet was too low, and it made it awkard to play the RH alternative fingerings. If this doesn't mean anything to you, have a look at the fingerings for the Bb soprano clarinet on
this chart... see the E key and the F# key at the bottom? - I found those keys particularly difficult to use on my old clarinet, but now with a higher thumbrest on my new clarinet, I find them quite easy. On any any clarinet you try, make sure you can reach those keys easily. If you do get a Hanson, ask if they can supply an adjustable thumbrest to go with it as you and your daughter may need different positions
