We have a chemical free yard that I also plant clover in. The high traffic areas are more clover than grass, which makes me think it holds up better. The clover also turns green earlier in the spring and stays green longer of we're having a dry spell in the summer. Clover helps keep the grass happy and the pair seem to do a decent job keeping dandelions down, but we have them in our yard too. They don't bother me at all personally and our kids like them. Thistles are not that common in our yard, but when they pop up I'll spot treat them since they're painful to walk on.
