Since both SD Realtor and I used to be with HelpUSell, I think we are fair ones to ask this of.
I was an office manager and left.
I think his office retired their franchise.
He can correct me if I am wrong (and I may be).
Strictly speaking, I would suggest to go with the business owner (not all office owners have broker licenses) rather than an associate licensee. I believe this because they would have more latitude to negotiate.
That being said, I think a better consideration is the synergy you feel with that agent.
I would recommend interviewing a few agents known for client rebates and see how you click with them, what their resumes looks like, and what rebates they can offer.
I think these are more relevant concerns than what is on their state license paperwork.
