Other popular options I have found in the cryptoverse for minting NFTs are as follows (thank you @illuminaticongo):
Opensea - "free" minting option on Polygon. Not sure if I like the idea of no real base value though.
2 Etherium versions known as Mintbase and Mintable, and they are planning on partnering with Immutable X to offer much lower gas fees. There is also a Zilliqua version of Mintables
And one on Solana called Solanart.
CONGO - Could you please elaborated on some of the finer points of concentration for each of these platforms (differences/advantages/disadvantages)?
Bless the method.
