There's not been a study on it as far as I know (maybe there's some polls online, though?), if that's what you're hoping for. Obviously it's going to be largely anecdotal but it's not exactly just Apple bias. It's notable because the remarks about the trackpad often come from non-mac users who painfully concede that the trackpad experience on MacOS is better. One example I can think of is Linus from Linus Tech Tips always using a mac trackpad as the gold standard to compare against in his laptop reviews.
