Its not that you can't find nice 6 lug wheels, you will just have a way larger selection if you go 5 lug. Also from what I've seen there is also more available if you go with the cars pattern of 5 on 4 3/4 as opposed to the trucks pattern of 5 on 5, but usually you can get what you need with the 5 on 5.
