Sophie's 66A+G is a strong grab with her best grab damage, wake up and the smaller break window. So why use A+G? A+G leaves you at +6 and doesn't push opponent very far away, so mix-up potential is a reason. The real necessity(I think) to make this possibly worthwhile over 66A+G is to be in grab range after A+G. Depending on the character and the action taken afterwards, there isn't any guarantee of this.
Not the best prediction exactly, but this list of character's who can be grabbed on neutral gives an idea who is more likely to be interrupted by a grab if they respond.
Neutral:
Lizardman
Sophitia
Amy
Mitsurugi
Taki
Siegfried
Nightmare
Xianghua
Kilik
Yoshimitsu
Algol
This list of who can be grabbed at immediately again if they block is more important I believe because you can make a convincing argument to your opponent for block at advantage.
Block:
Apprentice
Sophitia
Amy
Setsuka
Cassandra
Yun
Talim
Algol
A number of characters, but still not as consistent as one would like. Unless you're opponent either always attacks or can be convinced to always block and plays the right character, you don't really have grab to make the situation dangerous. Notably Algol, Amy and Sophie herself are generally in range after A+G so in those fights it looks promising. Amy can interrupt with 6B, but if you can bait highs you'll do well for yourself with Sophie so I don't think this is such a problem.
