I am on the fence between these two beasts, I see the differences in gameplay but an important point to me is the quality of the interactive in-game tutorial.
I have a limited collection of modules and while the ED ones have a comprehensive and spot-on tutorial (might not be the case for all their modules, but it is for those I tried), the third party modules sometimes are quite sub par in this regard (buggy, incomplete or with wrong information never updated after early-access phase).
My final decision will not be strictly based on this, I am quite aware of the ways they differ besides this issue, but this is an element of choice. So, can someone having both F-14 and F/A-18 tell me how they compare, strictly on this matter?
