Don't know a thing about Hanssem, but I do know that Kemper used to be one of the best companies around and has declined in quality over the last few years. Be cautious of moving forward with Kemper, and be sure to read the latest reviews about them that you'll find on Google and elsewhere. That's not to say you shouldn't order from them as Hanssem could be better or worse, but try to do more research on both if you have time.

Here's how my Hanssem cabinetry is holding up in less than 5 years. :( Being told that they won't honor any warranty either.

Except I don't think it's water damage. The dealer who doesn't sell this product anymore is the only one so far saying "water damage".

I do not recommend Kemper either. Our cabinets are maple with chocolate stain and the finish is wearing off horribly around the edges of the doors and the pullout recycle center. I should have complained earlier because they will not cover under their warranty. They are now 8 years old and look worse than the 20 year old cabinets we replaced. They obviously do not stand behind their product.
