I would classify them as a good family oriented brand. They may not be top of the line in everything, but they do ok for the person who goes out a few times a year.
I have been told the older lanterns and stoves are better as the metal is thicker. However, others have said the newer products are made due to consumer requests for lighter products.
I actually just bought a new tent that is a coleman. Just used it last weekend with the kids to see how they would like it. Was not bad, but I have used better tents. Got to admit the setup and take down was super easy.
