I own several bikes, and if I had to pick only one, it would be my touring bike. Drop handlebars are by far the most versatile type for all around riding. If your brake levers are set up properly, you ride most of the time with your hands on the hoods of the brake levers and you can use the brake levers from that position, if you prefer riding with your hands on the tops of the bars, you can install interrupter levers that you can reach from that position. You can install aero bars for use in a triathlon, and you can also install tires wide enough that you can ride off road like a cyclocross bike. A basket might be difficult to mount on drop bars, but a rear rack can mount open panniers that would serve the same function. If I could only own 1 bike, it would be my touring bike even though I own road bikes that are worth almost 10 times as much.
