Response to any drug varies with each individual. We may say that there are certain common responses to a drug with most of the people but still they vary in various parameters at an individual level to more or less extent. So we can not review a drug universally as the best or worst, like we can not do that for any commercial product , for e.g say a mobile phone, we can not say that which is the best one universally among few , but the best one would be like which suits you the most!
