Isosurfaces don't have the resolution problems of height fields, and are 
far more flexible, but can be a lot slower. One problem with height 
fields is that you are limited to upward-facing surfaces, vertical or 
very steep surfaces usually show artifacts, and you can forget about 
overhanging parts of the terrain...no caves, unless you do some fancy 
work with multiple height fields.
You weren't specific about your problems with the terrain...is it 
texturing, the shape of the land, triangle artifacts...
