It's a little bit less work to get a really nice paint job on MDF. I think most painters prefer it. The average person can't tell the difference after they're painted. Beyond that, I would not say MDF is preferrable. I rarely use the stuff because it's heavy, nasty to work with, and doesn't hold screws as well as ply or solid wood.

Something I left off of my last post to another thread similar to this one only asking about Kraftmaid. There are truly differences in the types of each. I would choose furniture grade board over Chinese plywood for instance. I have not checked yet to see if the all ply Mid C cabinets I'm looking at are chinese plywood. Likely they are cause the price is so low! Anyway we missed this at the home expo in March, but my sales guy told me they were there and had a goldfish bowl with both plywood and furniture board soaking for 2 weeks. They displayed it at the expo inviting everyone to try to break the furniture board, and no one could do it. The plywood was a total mess. It just depends. Whatever you get make sure it's the best quailty and I would think you'll be fine. I noticed for instance that the KM furn board was thicker and appeared to be better quality than the Mid C furniture board.

This has been discussed longer than I've been around here. (more than a decade) First you are much more likely looking at furniture board-aka particle board than MDF. The vast majority of cabinets do NOT use MDF but an enormous number of KD's, salesman, even contractors will refer to it as MDF. (but depending on type of each they would be on practically equal footing with particle having an edge over most of what is actually used for MDF in cabinets-there are over 100 variations for each) I currently only have one brand of frameless cabinets that offers Particle Board- they also offer ply and every other brand I have at the moment uses plywood sides. I went to great lengths to get that brand specifically for the particle board option. What I tell my customer- once you are at the middle price point, top end at the box store (Kraftmaid, Shuler...) there is no point in paying for plywood except: on exposed ends if that is what it takes to get veneer, and sometimes for shelves greater than 30" wide that will be VERY heavily loaded. So I'm telling them that when they go shopping somewhere else they should be looking at a less expensive options than some of what I have. When I worked at a place that had more particle board options available I told people exactly the same thing. I used to post the physical stats from the National Plywood Association for both- for all but bending under load, particle wins. Search back a few years if you want to see those. My own kitchen is particle board frameless because that is what I wanted and fit my budget. If I were to spend more I would not burn $$ just to be able to say I have plywood. There are far more important aspects to cabinets quality than "pepsi or coke" ply or furniture board. AND once you have settled on a price point there is more to picking who you work with than which brand-who provides it for you counts for more. As to the cabinets themselves- the most important aspect of a middle of the road or better brand is customer service and QC, finish is next, methods of construction and volume come in there (how rushed are the people on the glue line is my favorite thing to see when evaluating a brand- a really accurate indicator of how things will turn out in the long run).

You said you ordered the Doors wood with MDF panel - that will not eliminate the paint fissures from expansion and contraction - the wood parts will still move. The mdf panel helps because it is not moving but it is not the cure all. I have a company who does doors made of all MDF but put together like a regular door is and while the paint lines are minimal they are not marketing the product as not ever getting those lines. It will still be possible but much less. As far as chipping goes, I think that will happen no matter what the door is made of. Have a conversation with your KD and see what the real deal is and go from there....Maybe they will let you use one of the doors as a test... bang it around, bump it with pots, soak it with water, spill stuff on it and see what you think ( but you should try that with wood too....) Good luck!
