You would be hardpressed to find many bitcoin maxis arguing that monero isn't superior in its privacy tech.
The main criticisms usually revolve around:
1. Auditability "inauditable supply" (Nature of maximum privacy)
2. Tail Emission "infinite supply" (Future mining security)
My counterpoints to those is:
1. While true bitcoin auditability is simpler, it is not true Monero supply isn't verifiable. It rests on sound multi-decade cryptographic assumptions being correct. You run a node to audit supply just like bitcoin.
2. What makes fiat inflation particularly terrible is both high rate AND unpredictability. Monero will reliably and forever produce 0.6 XMR per block (predictable). And because it is a constant number, not a % of inflation, it is forever approaching 0% inflation (low rate). Monero is currently lower rate of inflation AND lower supply than bitcoin.
Last point is you dont have to be a maxi of either. You can use both for their strengths. Bitoin for longterm savings, Monero to transact fungibly and privately.
