I use Name brand foil liners because they help your cupcakes come out of the wrapper nicely. If you have some other sort of liner/wrapper you like to use, go for it. If your cupcakes stick to your wrapper, try the foil lined! They're awesome. I've never tried just baking them in the cupcake tin itself. It might work if sprAyed really well. Grandma Vera always used the foil ones and always, always walnuts.
