I'm lucky to have both of these and see the question coming up on why choose one over the other. It depends on the work you are mainly doing.
For working with sheet material, i.e. building cabinets, shelving, build-ins, etc., I would recommend the DDF40. It's reference off the flat base combined with the well thought out accessories make it very easy to learn to use and provides extreme precision. I have used it for a few builds now, using 19mm melamine board edged with 2mm ABS (using the Hit-M bander). I use the Mafell toothed rail for indexing where possible so sets of dowel holes across a large board line up perfectly, referencing off the back edge - the verticals are cut 2mm wider than the tops and bottoms, this means in the corners, the vertical edge 2mm round over lines up with the edge banding for the horizontal pieces. It's also perfect for using with the Lamello Zeta P2 and the Divario fittings for invisible slide in shelves - much easier that with the DD40P.
For working with timber section, i.e. small to medium frames, solid wood joining, etc., I would recommended the DD40P. It's easier to use off a pencil mark for framework, with the fence swung down to 90 degrees. I recently had some large cupboard frames to build and install, wood sized up on the Erika, a quick sand with the Eva, then loaded the wood up to take up the mountain. Was pretty tired and wasn't sure of the best way of assembling the frame on site - took the DDF40, DD40P and Domino DF500 with me just in case - ended up using the DD40P - it was so simple, set the plunge depth, drilled using the pins as reference and pencil lines for the rest. I had debated selling the DD40P when I purchased the DDF40 - but it so much easier to use on timber, I'll keep it. I have used this with the Mafell toothed rail too, I only have the short rail for now.
If I could only have one, I would keep the DDF40 - it really excels in sheet material work, it can be used for small framing work too - it fits in better with my workflow. Your mileage may vary...
