The only pollsters acceptable are those like ABC, CNN, and Marist, even though they are less accurate than some of the pollsters (such as Big Data, Emerson, and Trafalgar) that are routinely disparaged.
Just to be clear, the so-called "accuracy" of the "Big Data poll" comes from one guy's random tweet responses to Jack Posobiec. There's a reason 538 has them banned (even while giving high ratings to the other polls you mentioned alongside it).
Even Trafalgar mostly seems to throw things at the wall and see what sticks, if the absolutely looney-tunes polls they've put out this year are any measure. Maybe they have a better read on what's going in in the Midwest, which is classically their strongest region, but even there I think they've just ended up getting lucky by predicting substantial Republican overperformances in years where they incidentally ended up happening.
They gave the best case scenario for Republicans and they were right. Republicans turned out based on their candidate being a celebrity.
