Tinbergen is clearly the better institution. However, the quality of life at each university is extremely different, this should definitely be taken into account. Tinbergen placements seem much better. But if your goal is a good liberal arts college or private placement than WVU should be fine, they also have some decent faculty (however WVU doesn't seem to rank very well at all). Assistantship duties (depending on the school) are pretty modest and is the common form of funding for US institutions.
I would examine your reserach interest and career goals as each institution is very different.
