I don't think you're wrong (but of course I am quite biased)
I remember feeling as I left Roman Catholicism that it had only ever talked about things that I was now given the tools to manipulate. Orthodoxy understood my sins at a deeper level and was more ready with hands-on, practical information on combating them, which funnily enough often relied upon my giving up control. In Orthodoxy I believe I was truly taught how to pray, and the importance of it.
Not that I did not pray as a Roman Catholic, and not that I think those prayers were anything like in vain, but Orthodoxy, I feel, taught me to pray at a deeper level, and why. Truly that has made the difference.
