Just Play the Bloody Game
I am the sort of person who feels a need to hedge his beliefs. 'I think that maybe ___', 'For me ___', 'I like to ___'. Today I'm not going to do that.
If you spend more time thinking about, reading about and dreaming about playing DnD than you do playing DnD, you are doing it wrong. You are not engaging with the hobby in a meaningful way, and certainly you are not equipped to offer meaningful advice to someone who is engaging meaningfully in the hobby (i.e. running or playing in a game!).
This isn't a moral failing or anything, it's okay to do something wrong, but I'm not going to pretend it's the best way to do it either. You're not evil if you spend more time reading cookbooks and watching Food Network than cooking, but you're not a cook either.
The good thing about this problem is that it has an obvious solution! Play DnD! I guarantee you that, no matter which module you run, you'll have more fun than if you continue debating which to run!
