All other things being equal, which is better if you need to place a
64-bytes into the Bitcoin blockchain? A traditional OP_RETURN or a spent
taproot transaction such as:

OP_PUSH my64bytes

I know that the anti-OP_RETURN folk would say “neither.” But if there was
no other choice for a particular protocol, such as a timestamp or a
commitment, which is better? Or is there a safer place to put 64 bytes that
is more uncensorable but also does not clog UTXO space, only spent
transaction `-txindex` space?

My best guess was that the taproot method is better, but I suspect there
might be some who disagree. I'd love to hear all sides.
