Filmore Seating Question.

Hey all. I’m looking to buy tickets to a comedy show at the Filmore. And I’m still kind of confused how seating/ticketing works.

I know the upper level has seats, but that’s too expensive. My understanding is that the Floor is just a general admission free for all? Everyone stands. There’s no real seating assignment? Or am I mistaken?

But on stubhub, tickets are listed in rows (Row A, Row C, Row T, etc).

Does it matter which row I buy a ticket in? Will I actually be closer to the stage?
