Personally, I think that Matrix+ is the best offering that Matrix has.
The only thing that comes close is the holiday course, but in that you don't get official support/assistance throughout the term if you need it (but if you do go that way, hmu
).
I think Matrix+ is good because you can speedrun the whole term's content in 2 or 3 weeks and if you get stuck, you can message on their own Matrix+ forum. I think the forum is better because you can get a better thought out response than one that the teacher comes up on a whim during class.
I quite like the teachers for Matrix in-person classes because they are professional and qualified, however the students in the classes are not the best to learn with - this is true for almost every tutoring centre except for ones where you have to do a test to get in. Because of this, I didn't mind the online environment, except that it does get draining if you 'binge' too much matrix+ at once. To be honest, matrix+ is better than (or at the very least on par with) UNSW mathematics in terms of student support and resources.
As for the alternative, I liked the holiday course and the students in your class are pretty hardworking (they sacrified their holidays to be there). However, I didn't have a private tutor so if you have questions during the term it can be difficult to get an answer.
Good luck
