Most of the differences between the pins are cosmetic. Molded barrels, Smaug, armor, decals. The moving axe / sword on the slings is the only mechanical difference I recall. I owned the standard and never felt like I was missing much vs the upgraded models. It’s is all personal preference and some people really like the cosmetic differences. For me, i typically go for the standard / pro models unless the differences are drastic (so I have some more $ for additional pins). That being said, LE versions can be found around the same price as some of the standards I have seen. I have seen prices vary widely based on location and it does seems that the standard version is harder to find than the LE in the used market.
