Welcome to the site, estelle! This site is full of excellent information - I hope you enjoy your stay!
To your question...
As others stated, tires are a product of compromise. No tire model can score 10 out 10 in all performance areas (I.E. Road Noise, Wet Grip, Handling etc). That being said, the right tire model for you really boils down to your driving conditions and the attributes you expect your tires to deliver.
This may seem like a silly question, but why are you in the market for new tires?
