Interesting, learned something new.
So which seed generation is more widespread? BIP39 or whatever Electrum uses?
BIP39
Also if using BIP39 which Derivation Path is best to use in terms of future compatability?
BIP32
BIP44
BIP49
BIP84
BIP141
Iancoleman is not supporting BIP86 yet which is pay-to-tao-root. If you use wallet like Sparrow, you can go for BIP84 or BIP86 because it has low fee transaction.
