This is where I am going to sound really blunt, but don’t waste your life trying to impress other people.
This is where so many people go wrong with their legal careers. I have seen too many people make too many mistakes purely for this reason.
You should do what you want in life, not what you think other people would expect you to do because of some general perception on brand/prestige.
Working in law is a challenging career no matter where you go. Do you really want to risk you satisfaction on a day to day basis due to your work and environment just because how others perceive your employer (that’s not even how they perceive you!)?
If the only thing that makes the “better” firm is prestige, then I truly don’t think they are the better firm for you. And that is what’s really important - finding the better firm for you, not who a broad sweeping survey of students/lawyers think would be better just because of their perceptions of an employer brand.
