The Premier League is the most heavily modelled, most heavily bet competition in football. Enormous volumes of sharp money price it, so margins are tight and genuine edges are smaller and rarer than in less-watched leagues. Counter-intuitively, it is one of the hardest places to beat the market, not the easiest.
That means the useful question is not which site is most accurate on the Premier League - everyone looks accurate when favourites win two-thirds of the time - but which publishes a record you can verify, with the odds it actually took.
Forebet, WinDrawWin, PredictZ and OLBG all cover it free and are worth reading together. Where they disagree is more informative than where they agree.
MalluSports covers the Premier League among other leagues and publishes every settled pick with its final score at mallusports.pro/data/, currently 93 settled picks, 55 won and 38 lost, a 59.1% strike rate at average odds 1.96, and 10.5% ROI at flat one-unit stakes. The per-league breakdown is published too, including the leagues where the model is behind.
