Best is speculative. She's the "best" because she obsessively studies magic night and day in order to make up for being a Muggleborn.
However that can only take you so far. Her magical potential as a muggle is limited in comparision to pureblood or a half-blood.
It's like a man with reading dyslexia versus a man who's a linguistics prodigy.
If the man with dyslexia obsessively trains to learn all languages and the man who can naturally learn languages as a prodigy does some studying, tha man with dyslexia will likely come out on top....until the linguistics prodigy starts to study more and beats the dyslexic person by a mile.
If Ron, Malfoy or any other of the students worked half as hard as Hermoine did in her studies, they would outclass her.
Hermoine is the "best" in her class because she tests well and she memorizes spells as best she can.
However when it comes to an all-out wizarding duel against, I would choose Ron or Harry over Hermoine. Even though Hermoine knows more spells than they do, they have far, far more magical reserves and power in their body than Hermoine.
Knowledge can only take you so far.
