The difference is that none of these features have been endorsed by Bitcoin protocol developers, just like Omni/RGB/Taro/Lightning Network weren't endorsed by them either, which would've meant that they were willing to integrate these features alongside the protocol designing specifications.
I mean, I thought Ordinals were cool, but this: https://brc-20.io/ list of "inscribed" stuff is garbage, and it looks like some exchange listings for a bunch of shitcoins rather than any NFTs. In fact there aren't any pictures at all. Where there used to be real "Pepe" inscriptions, there are now "1000 claims for $PEPE ordinal"-style JSON data. There isn't even any technical whitepaper for the standard and the "design" exists solely in vague tweets.
