If you will only be using the trailer for around town like groceries and errands, the Burley might be a better choice, bu the BoB still works very well. For touring on road, or mixed conditions, the BoB is the way to go in my opinion. The single wheel allows the trailer to track very precisely behind the bike. If you need to swerve and miss something on road or trail with the bike, you don't need to worry about the trailer, if the rear wheel misses the trailer will too. The BoB handles more like an unloaded bike than the Burley. The Burley tries to drive the back of the bike a bit more than BoB. The BoB can be a little cumbersome when it is off the bike, but in real-use you will quickly get used to it, and it isn't really a problem. The BoB has less rolling resistance (one wheel vs two) and one less tire to worry about flats with. (In 5,000 miles with 50 pounds we only had 2 flats with the BoB) Also, the BoB is a little narrower overall than the Burley because it doesn't have tires stick out the side. This allows the BoB to work in more tight situations (narrow bike lanes, small shoulders, elevated footpaths etc) than the Burley. The BoB may put some torque on the rear triangle of the bike, but with a properly loaded trailer it really isn't a big deal. The one tire allows the trailer to ""lean" along with the bike. With both trailers, learning how to load them correctly (keeping the weight low) is important for long distances.

For touring, I would go with the BoB.
