The tower on a chest freezer would go out through the lid. That makes it harder to open if the back of the kegerator is against a wall. Also, towers are pretty pricey, so depending on the number of taps you want, collars can be a lot more economical. The collar allows you to run the faucet shanks right through it, without the expense of a tower, allowing you to put that money into more taps. A tower with 2 cheap faucets might cost about $250, you could easily get 4 good faucets and shanks for that price, and the collar price is minimal.
Plus, there's the issue of keeping the lines cool in the tower that you don't have with a collar.
