From friends which have it, it has a dull (non-glossy) appearance, scratches relatively easy and can be impacted/damaged by hot items.
I know one friend has said they wouldn’t get it again due to the costs and indicated it would be cheaper to get laminated (laminex type products) benches and replace them after 10 years if one gets bored with them or to freshen up the kitchen.
In relation to advantages, one needs to think if they really apply based on one’s own past kitchen experiences.
At the end of the day, it is a personal preference as Corian will last a long time, like other bench surfaces, if looked after when using.
