Most people feel that above seat steering yields more precise control of steering.
Above seat steering lets you use all standard bicycle accessories, like computers, lights, small bags, etc. without special mounting. Above seat steering also gives you a convenient place for maps and a camera when touring. Yes they can be lighter, but at the expense of ride comfort and limited gearing.
