I fitted two IKEA kitchens to past homes I lived in, 14 and 17 years ago. Not professionally fitted either, I did the hard work.
I found the properties had both recently been sold and had a look at the listings - both of the kitchens were still doing great.
The kitchen I fitted had solid oak door frames with a veneered panel, Quaker style if you will, with standard chipboard cabinets.
