Best pdf readers software?

Checking out some options but these all seem too featured or too expensive and I wanna know whats out there before I bite the bullet on anything. All I need is something that can process a PDF well - not get jumbled up on the footnotes and whatnot - and read it accurately. i dont even really need it to be a fancy AI voice, the old voiceforge TTS would serve me just fine, in fact I would actually prefer that for nostalgia reasons (long story). Hooking that up to a local OSR would be the dream but I don't know how to code that. Just let me know.
