I suspect the difference comes down to toner, I lucked out and the stuff in my current printer seems to melt at a relatively low temperature and bond very well to copper. Some toners don't work nearly as well and unfortunately this isn't something you can typically find out without actually trying.
For double sided boards I get excellent results by cutting the paper for one side a bit smaller than the other, lining it up perfectly and then taping around 2-3 sides to make a sandwich into which I slip the board. If you have trouble with the board shifting, folding it between a sheet of plain paper and running the whole package through the laminator can prevent that.
