We used Home Depot and got Kraftmaid cabinets for the kitchen, pantry, master bathroom, and linen cabinets. They are very well-built (our installer, who is also an excellent cabinet builder was very impressed with them), and they are made in the USA, for those of us who care about these things. You can get them in 3/4″ plywood for all boxes, or just those around sinks and dishwashers.
We got a LOT of cabinets and had all of them built with 3/4″ plywood, so could not really compare to what you are doing, but I highly recommend taking your plans by them for a free estimate and layout. They can also make slight modifications to help things fit better. You might also check with Lowes as they have the same cabinets and seemed to have more displays so you could see how the different cabinets worked together and get some good ideas from the physical displays there. HD was just closer for us, so more convenient.
Overall, we are very pleased with our cabinets, but got white ones which do tend to chip. I’d recommend going with natural wood colors.
Kraftmaid is KCMA certified as well, from what I can see:
