Default Dx engineering 1:1 balun or ugly balun?

Obviously, i like the cost of building an ugly balun, but will it work
as good as the 1:1 dx engineering balun? Thanks in advance.

Here's some information: http://www.karinya.net/g3txq/chokes/

As you can see, there are none of the air-core baluns that work very well 80m-10m because they are narrow-banded. Note that 25 turns is not enough turns for 80m and too many turns for 10m. Compare the bandwidth of the ferrite toroid baluns to the bandwidth of the air-core baluns. (We might define that bandwidth as any color except red, i.e. any frequency where the choking impedance is greater than 1K ohms.)
