I'm not really sure why people are prepared to compromise on tyre choice for the sake of a couple of hundred quid tbh.
In the dry there is masses of grip and in the wet there is a lot less. From a safety point of view it is worth trading some dry-weather grip to improve the wet-weather performance.
Over the years there have been a couple of occasions where I have come to a tire smoking stop and there wasn't 6m of road left. This is several accidents I didn't have purely due to running premium tyres.
