update: Jax2 nailed it terms of sound. Well done.
What to keep? Apples vs oranges. On balance the Sonatina II presents a fuller picture of the concert. I am still likely though to keep the 17.5 because (1) it's new to me, and the fun of the hobby is moving on from pieces periodically even that you love them, to try other stuff. Also, (2) the smaller speakers don't dominate my living room quite so much.
Both of them have the family sound of Silverline, which works incredibly well for me.
