No need to study the whole thing. But I advise you scan through the reasons each firm achieved their rank, so that you can get a sense of what is important when considering an investment partner.
I recommend using Fidelity because it scores highly in all categories and most importantly, it has low costs. Additionally, their nation-wide offices allow you to easily schedule a visit should you ever need in-person advice.
