I occasionally make tables, and usually clamp the legs to the apron (or top, depending on the design) using band clamps. You know - the band of fabric that's cinched tighter with a ratchet. I wrap the band around the frame so that it pushes the legs into the apron at all corners, and I think I achieve pretty good joints that way (usually mortise and tenon). In reading another post describing their abundance of bar clamps, it occurred to me that perhaps there's a reason that people have so many bar clamps, but don't mention band clamps. So here's my question: is there any particular advantage to using bar clamps rather than a single, easily managed band clamp for this purpose?
