Michelin makes good quality tyres, they give good grip aka better traction and braking, fuel economy, low road noise and they also last longer. The only good equivalent in terms of value for money I can think of would be Kuhmo Solus KH17.
Now I have no idea of what you mean as a better alternative, as the michelins are good all rounders. If you want more grip as in a softer tyre, you will compromise on mpg and longevity which ends up costing more. But in that case, toyo tyres... If you still have some thread left, keep the michelins.
all that said, the michelins are only 41 per corner on here:
