I usually have woodenware with me to house a swarm but a lot of times the cardboard box trick works best for me.
1)I am in an area where its not uncommon to catch 5 or more swarms in a day, so you could run out of woodenware quickly, the box works great for temporary housing,besides if I kept every swarm I caught, I would have way more hives than I could keep up with. Its easier for me to drop the boxes off to my friends or other people looking to house a swarm.
2) As pointed out by Konasdad,cardboard or plastic boxes are much lighter than woodenware, hence much easier to use when shaking a swarm into while you're up on a ladder.
Of course having both, woodenware and either a nuc or a deep or medium on site is a great way to go.
Finally, if you look at the above pic, there is a square cut into the box. Once the vast majority of the bees are in the box, I use my smoker to puff a few inside, then duct tape the entrance, secure the top and you're ready to go!
