Italian game vs scotch game

IM pfren , I'm in an idea to change my opening from Italian game to something else that's why I commonly asked is that Benoni opening is good. I don't know about the several kinds of it.
Huh?
The Italian game is a choice for White when Black answers 1.e4 with 1...e5, while (any) Benoni is a choice for Black when White opens with 1.d4.
There is hardly any relation between them.

Learning and extra opening isn't bad right?
It depends on your definition of "learning".
