According to the manufacturers sites some of the Michelin energy+ are rated B for wet grip, others are A. It depends on size, and it is not simply a case of the tyre width. Rim size has an influence as well.
The Avon ZV7's are all rated as A for wet grip, irrespective of width or rim size.
The Michelin energy+ tyres appear to have better dry grip than the Avon ZV7's but no ordinary motorist should ever get anywhere near the limit of grip of a tyre in the dry, so that doesn't really matter.
According to the numbers, Avons are a ba' hair noisier.
