I like this Scorpion better than vanilla because this one has very good buttons across the board overall.
The standing 2 is 9f instead of 10, so flame aura links have 1 relaxing frame which makes much easier to connect.
It has a 7f normal which compensates for his lack of range on most of all his normals.
Has better plus strings which doesn't give away his pressure right away
The block string its not guaranteed but there are ways to make it so, and when you really scare off someone to press buttons or input moves, instead of minus you'll be plus, instead of gaps, you become gapless.
The two only things XL scorpion doesn't has that vanilla does is: two flame auras combos, guaranteed 214 blockstrings.
