Very good question.
I like this style a lot and tried it on in store two times.
I went for something else every time.
It is quite structured at the bottom and tapered at the top- like the Alma bb which I bought instead the first time, because it is a classic and the Siena is not. Price was better as well and you get a a lot of details (Lock, key bell, leather bottom) with it.
Second time I tried it on I didn‘t buy anything but when trying on I figured I would use it like my Speedy B. So it seemed too similar... thats just me.
I ordered a Neo Noe instead after the store visit,....
I would still buy it, but the price increased immensely on that one over the last two years. But it is very unique and functional.
