I am retired so I don't commute any more, but when I did commute I did it on my race bike the years that I had one. Before that I just had a general purpose do everything bike. I always considered the "twitchy" handling a plus. The drawback was that I used tires that were a bit more flat prone than what would have been on most touring bikes so I had to allow enough time to fix a flat just in case.
I rode the full on touring bike on several tours and gradually feel out of love with it. Then I started touring on sportier bikes and eventually stopped riding it altogether. I haven't seen it in a few years let alone ridden it. It is still with a family member as far as i know, but I don't expect it will ever come back home to me.
