I gauged my decision with several factors. 1) Instruments like Flute, Bassoon, and Oboe have a long history before the romantic era, thus they have a strong reputation with the baroque and classical eras. Flute was pretty much abandoned as a solo instrument in the 19th century, and I imagine other winds too.
2) I find wind instruments to be the most human of all instruments. They live and breath, literally. Thus, they can express more human emotions, imo, because of the kind of physical limitations they have. Being closer to the human voice, wind instruments they are like that.
3) The clarinet is a relatively young instrument, and its solo repertoire is rich during the early, middle, and late romantic eras, more than most other winds (by that I don't just mean solo repertoire, I include orchestral excerpts) The Rach Symphony no. 2 for crying out loud!
Thus,
I voted clarinet.
