Postals vs Traditionals

Winter. Oh winter. It can be quite difficult to letterbox in the snow. Luckily, you can still "letterbox" through the mail!
There's some upsides and downsides to postals. In the winter months when it's too cold or too snowy out, postals are a great thing to do. You sign up on a postal tracker and wait for it to be mailed to you.  It brings the box to you during the winter months. In the package is a stamp and a logbook just like any box, except there's no actual box.
I have done three postals so far and I enjoy them. I love going out to my mail box to discover a letterbox inside my mail box.
But with postals you loose the satisfaction of having to wade knee deep in brush in search for the box.

So which do you like? Postals or traditional letterboxes?
