OED is a house rule package for OD&D which attempts to incorporate a number of more complex concepts which later made it into AD&D, in cleaner and simpler fashion. You expressed frustration with your own efforts to come up with a simplified system for B/X, and I thought this one might helpful to look at.
Rather than getting into the weeds with you on the attributes of specific weapons, I'm going to note that any given system is necessarily going to represent some compromise between complexity/simulationism and simplicity/speed of play.
For my money, the OED system is one of the more elegant takes on weapon vs armor and on mechanically differentiating weapons in D&D. More playable and interesting than those in either version of AD&D.
If you prefer Moldvay and co's design choice to scrap those factors entirely a la B/X, I can totally respect that. I may be lucky that my own sense of verisimilitude does not put me in a position of thinking "everyone should just be carrying warhammers!" I'm happy enough with a system like this one which provides a pretty balanced range of options and I find it close enough to representative of how the historical weapons work, albeit I could make a few tweaks here and there if I wanted to nitpick.
