Monero is good with it’s privacy features. Also, they have some good features inherited from the bytecoin design: smooth emission curve, dynamic blocksize limit. But it has disadvantages anyway:
Transactions size is ten times larger than in bitcoin. If monero has as much txs as in bitcoin its blockchain will growth ten times larger and/or fees will be significally higher;
Lack of infrastructure and real world use. Breaking changes happen often and prevent from integrations in apps;
No active develop or research of Lighning Network/payment channels or other scalling solutions like sharding. Lack of activity makes onchain txs enough. LN cannot be activated in one moment by pushing a button. It needs channel infrastructure, routing network and apps to be created;
ASIC resistance PoW algo makes 51% attack easier. With a block reward reduction to it’s minimum in 2022 attack will be even cheaper;
Benefits for early participation with the emission curve make it harder to get adoption.
Monero is superior to all of these cryptocurrencies anyways :artist palette:
