What Artist's fanbase is the best and Worst ?

For the best I would say AJR lol . I Know they get a lot of shit online but their fans just enjoy their music . Most of them I have met online or irl are really nice and i do not think they give a damn about the hate they get .

King gizzard , Foo fighters ( are very passionate mind you ) , Imagine dragons , Metallica are some more artist's that have a generally good fanbase .

For the worst it is easily Swifties .
