Which is more scariest between philosopher stone, chamber of secrets an prisoner of azkaban?

i find prisoner of azkaban the most scariest between the three as there were alot of scary scenes in it....between chamber of secrets and philosopher stone...i found that chamber of secrets was more scarier...philosopher stone was very little scary when harry goes to the forest and voldemort went after him....compared to chamber of secrets when harry goes to the forest to see the spider...it was even more scarier..and in philosopher stone when harry goes to the dungeon and when the two headed man's had showed up that also very little scary and compared to chamber of secrets when the basilisk had showed up...it was way more scarier...as a result philosopher stone and chamber of secrets had 2 scary scenes according to me
