They are the same thing; you can tell because "valid" and "sound" are synonyms for each other.
When building arguments of importance, is it more important to be valid or sound?

Well is it more important to be vaild or sound?
If you are valid, you are also sound.
A valid argument is a sound argument. A valid argument is based on fact; a sound argument is based on fact.
Conversely, if an argument is not based on fact, it is unsound, not valid.
There IS no difference.
A valid argument is a sound argument. A valid argument is based on fact; a sound argument is based on fact.
Conversely, if an argument is not based on fact, it is unsound, not valid.
There IS no difference.
Another word for valid is deductive. Technically, they are close in meaning. However, they are not interchangable. Deductive (or valid)refers to how the conclusion must absolutely follow given the premises. Sound means that the premises and the conclusion are all actually true. I have to disagree with the both of you.
You're right Brandon. It is more important to be sound than valid when building arguments of importance.
