I've got both the Cuisinart Handy Prep DFP-3 and the KitchenAid KFP1642CA...
I got the KitchenAid because it was too good of a price to pass up on SurLaTable, but I wish I wouldn't have purchased it.
It works fine. It is so big and there are so many accessories that the accessory garage takes the same amount of space that the unit takes and that's not counting all three work bowls....
I've started using more attachments (RVSA) on my Commercial KitchenAid Stand Mixer just because those are easier to clean than dealing with the Food Processors. Aside from the amount of space the KitchenAid takes up, I absolutely 100% hate all of the interlocks and safety features on it. I get it, don't run it with the lid off, but when you have to fight longer with the lids to get them cleaned and get them aligned and locked, I more than likely could have hand processed everything in the same amount of time...
If Bosch comes out with the MUM5 for North America, that will solve most of my needs. I bought a BlendTec thinking I'd use it... That thing is so damned loud I won't touch it. I am trying to find a decent priced sound enclosure for it. The frequency the motor runs at just rips my ears apart.
Anyways, if I were to buy something again, I'd buy a used RobotCoupe with at least a stainless work bowl and a plastic work bowl or I'd get a MagiMix.
If either of those are unobtainable, I'd buy an older Cuisinart that I could still get parts for. Maybe even one of the new Cuisinart or KitchenAids with simple controls and not a lot of attachments or accessories.. Simple is better.
