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.
3. Blockchain size "unsustainable bloat" - NakamotoX is correct, forgot to add this criticism.
Counterpoint:
There is a disconnect in vision. Bitcoin maxis believe in hyperbitcoinization global adoption so they put on those same glasses when looking at Monero. This sentiment is not present in Monero community for the most part: "Monero is for anyone, not everyone" - Most likely, the entire world will not use a single currency even with crypto, it will be stratified now (and thoughout human history) just like fiat currencies.
A few more things...
-Bitcoin is only lighter *IF* you aren't using it privately. As soon as you coinjoin it is larger per transaction than Monero. So, unless you want to be serveilled 24/7 Monero is lighter.
-Monero has already greatly reduced it's tx size since inception (~80% reduction). In all probability it will continue to do so. The next update Seraphis will further reduce the size of transactions and make it easier to implement further reductions in the future.
