I really have liked Fidelity over the 14 years since I retired. Like you I had my retirement funds at Fidelity (inertia,since they manage UC’s plan) but also had a brokerage account at Vanguard. After a while it became obvious that there was no real reason to have both. Fidelity’s bond & CD chart also makes it very easy to compare all the types – US gov’t, corporate, munis, agencies, etc.
