EK audio osmosis vs TPR

I'm not sure whether this has been discussed but for anyone who has listened to the EK's AO 'actively' do you think it was as beneficial as taking a TPR/kaplan course. In other words, would saving $$ by purchasing AO give you relatively the same chance on performing well on the MCAT as taking TPR's class. (all else being equal of course.)

I ask this because I bought AO but I'm having second thoughts on whether I will score as well if say I took TPR. I know you are given access to FL exams...
