I think the over the counter parts dept trim upgrades they sell are different from what is found on an LE game, and the LE playfield features usually can’t be added. Ie game of thrones mini playfield for example. I also think you need proof you own an LE to get parts for one.
I prefer the get the LE version to have what the designer originally intended to be on the playfield, and also like having different trim, art and backglass. Hopefully it won’t drop in value as much as the lower trim level machines, but only time will tell that. I usually keep games for a long time though, so albeit not a huge concern it is something I’d like to think is going to keep decent value
