<prompt> Human: Ill keep it short and sweet.Ive used Fidelity in the past. I found their customer service outstanding, and their online interface very comfortable to use. Ive never used Vanguard, but, based on what Ive researched, it seems like a lot of Vanguards mutual funds and ETFs are consistently 10 - 30 basis points cheaper than many of Fidelitys. Im just talking broad index-based funds.Anyway, Id love to hear your thoughts.  <response>: Vanguards Admiral Shares and Fidelitys Spartan funds are nearly identical in expenses and composition. Youll be fine with either one.
