Monero inflation is not a fixed percentage. It's disinflationary tending against 0 over time.

Supply is currently smaller than Bitcoin even more so since its delisted from CEX which means no more fractional reserve shenanigans.

Inflation is currently the same as Bitcoin and about half of gold at around 0.8% per year.

There's a trade off between Bitcoin and Monero auditability.

There's also the privacy/ fungibility trade off.

There's an ASIC vs CPU decentralisation trade off.

There's tail emission (disinflation) to make sure there is enough security budget and not a wildly fluctuating fee market when subsidies become negligible.

There's also a trade off when it comes to quantum computers resistance where Monero has lesser work to do.

If you trust well understood mathematic assumptions and can live with disinflation at a rate half of gold inflation Monero is for you. Especially if you need a private store of wealth. If you are demanded to transact in public want to be absolutely sure (outside of custodian fractional reserves) that supply has not been tampered with and you need a deflationary asset (after losses) then Bitcoin is for you.

Most OGs from 2009-2012 own both and balance according to their needs.

Monero inflation is a constant amount (0.6 xmr every ~2 minutes)

So in relation to the total supply the % inflation is constantly falling closer and closer to zero (but never reaching it)
