It's in general in good practice (at least for me) to always super jump. It stabilizes on all characters except Rachel, which may need a j.b (2) in between the combo.
As for the distortion on Tager, you do at times need to change your combo up. If all the hits get in, you can end with 6b > j.6d.
Since CSE character specifics have been more or less out the window. Usually if something went wrong then it's a spacing specific matter rather than the character.
