Pulling-counter attack

Hi, Can someone experienced with this line please provide some insight to it for black? I'm looking at this as an opening line to practice as black and would like to know the possiblilities and chances black has against white in the scotch opening

I like this video overview: https://youtu.be/5QLgVdlgJqA?t=1872 

I don't like this line for Black. I don't think the pawn is worth having to shuffle around your Queen and King so much in the opening and giving your opponnent so much of a development advantage. I certainly wouldn't call it a counter-attack, but the annotaters there are pretty strong and booked up and think it's playable.

This variation is bad for black, don't play it. You win a pawn and then suffer. Black is fine after 4..Bc5 or 4..Nf6 or 4..Bb4+. 

It is a great variation, at least against weak players. You win the pawn and gain in time against somebody who is surprised by this. I almost always win these games
