SF is not on my preferred bidder list. I avoid doing business with companies who have tied agents, who are basically employees of and advocates for the company. So if there are claims problems they are not there to help the insured. Hard to evaluate from anecdotes, though, the degree to which this is an issue in any one case.
With independent agents I have an advocate who can swing his clients away from any insurance company that causes problems. IMO that is far more leverage and easier to employ than anything a tied agent has.
Getting off topic since the OP was asking about SF specifically, but there's pros and cons of independent agents. Those are easily Googleable.
Finding an independent that's honest, knowledgeable, and truly independent can be difficult since commissions are in play.
Aside from customer surveys and anecdotal stories, I don't know how independent agents can identify insurance companies that "cause problems". Any large insurance company is going to have some anecdotal claims complaints.
