It’s not just about whether or not it’s PoW or not. Many shitcoins are PoW. Dogecoin and BTC Cash are PoW.
PoW is progressively more secure the more mining that happens. This is one of the equations in the Bitcoin white paper.
Comparing the PoW of Bitcoin to the PoW of a shitcoin is like comparing a wooden box to a metal safe. Sure, both can secure your funds, but one is far far far more thermodynamically secure than the other.
