if you are talking about mining centralization, you have no right to flex, suitcoin had centralized mining for years.
more important point is bitcoin decentralization itself, everyone running their own node, validating blocks, deciding mining rules.
bitcoin now has 300KB block size, which reduces block growth. it has history of nodes being in control and not following what the foundry and antpool with its friends. invalid blocks are invalid.
suitcoin has big blocks, history of being a cuck to the mining cartel, and running a node is getting harder everyday.
mean while bitcoin is building good bitcoin apps that prioritizes decentralization.
meaning it cares about keep the global ledger small and easy to run, so everyone can have their own instance of the chain, and can very the txs and blocks for themselves.
