If you exclude all of the flaws of one implementation and include all of the flaws of another, then of course you can say one is better than the other. But that's not a fair comparison of implementations
CSRF has incredibly simple mitigations with cookies (SameSite=strict) and can even work across different path segments (although this tends to be uncommon) and has mitigations against XSS which local storage does not. XSS is bad in either case (CSPs aren't usually an effective mitigation for a variety of reasons[1]) but being able to outright steal the session token is worse than being able to use it in a potentially more limited context
[1]: Primarily that they're generally just not implemented and that a lot of web frameworks require incredibly loose CSPs up to and including unsafe-eval since they often need to dynamically load JS. In addition, this doesn't protect from supply chain attacks (JS that is injected as the result of it being loaded from another domain, like from a CDN for example).
