I have not. My playing significantly improved from the course Beginner Guitar Academy. It is a unique hybrid course. Very structured program with video lessons, but you have access to the instructor anytime you want. You can ask any questions, send a video of something g you are having a problem with, etc and he will respond, typically with a video. You can also schedule 1 on 1 video calls with him.
The other thing that sets BGA apart is that you must submit progress checks and level assessments before you can move on. It makes sure you have developed the skills needed for the next level and have learned what you were supposed to learn. He said he got the idea from the colored belts in martial arts. You have to prove proficiency before moving to the next level.
I do think that augmenting TAC with some other means of instruction is important.
