128 of entropy vs 256 bits of entropy. Dunno if it's "slightly". To me it's just more future proof, harder to crack. Possibly easier to split if someone was doing crazy multi-sig more words, more chunks to divide amongst plebs some exotic scenario. I would go with 24 for higher fund amount. But I'm dumb. Let the bitcoin gods chime in 😅

Technically it is a lot more security, but realistically it seems to not make such a difference on a day-to-day human level.. I like the idea for having 24 word for long term, bigger accounts.
