One difference is that non-KYC tends to be more expensive. However, I find a few bob difference is more than worth it for not having to explicitly disclose ID info to private companies. Not trusting those fuckers to protect against data breaches.
The value of crypto is that it adds a layer of "oh shit, we can't automatically request and verify the nature of this transaction" to paying for things. Of course, people might see your bank account and they might interpret "gee, what a lot of random small one-way exchanges" as "buying drugs". But, unless you are a kingpin illicitly moving millions of dollars* about, ain't nobody spending time and resources to chase you down.
*And, to be clear, it is the tax man who is upset about the king pin's millions, not law enforcement.
