Lots of reasons.

Most shit coins are proof of stake. This is more appropriately proof of wealth. The current richest people receive a disproportionate share of token/coin inflation and transaction fees with little to no cost or risk to themselves. Proof of stake cryptos are just simplified versions of fiat with different rulers. These rulers can simply vote with their wealth to change the system however they like.

Proof of work is a critical component of Bitcoin and it ensures that to increase your wealth (in coin count), you must work for it. There is no advantage for people that already hold lots of Bitcoin. Bitcoin is rules without rulers.
