Completely depends on what you want.
If you want an Optionfile with the Bundesliga and the majority of the Championship teams in it then go for Daymos. If you want a really solid Optionfile with great kits but no extra teams then go for Dragonskins. However if you want an optionfile with realistic stats for the Bundesliga then go for Edgars.
As I said, depends on what you're looking for.
