It would still be nice to have it both ways. Keep the grouped by product type but also make the collection name clickable to show the entire collection if a client wishes that.
I personally don't like the "xx styles available", I believe the customer would feel less lost if they could see all the products and make comparison decisions on the same page rather than going down the rabbit hole. However, designers sometimes have many products in the same style/colourways - granted. Also, I (as a designer) cannot control what image is shown here. Maybe it is controllable but only by being fastidious about the order of products as they are published.
