My bent is way more comfortable than my upright bikes ever were. I use my bikes 99% for commuting, so racing isn't something I do, but I do like to get to work faster if it is also within the other parameters of my riding.
The only thing sore after a long ride now are my legs. I no longer have wrist, shoulder or neck pain from riding. My bent is a tiny bit faster than my old road bike, and they are about the same weight (within a couple of lbs when outfitted for commuting).
I also now have a Strada velomobile, which allows me to ride even in very cold weather, and ice and snow without being ridiculously uncomfortable and is safer because it's fully enclosed, and 3 wheels.
