I bought the Incra table, Incra lift, and the PC7518 motor a few years ago. Setup for a wide variety of cuts is easy, accurate, and precise. Plus you can do half-blind and through dovetails for a variety of sizes and spacing easily. My results with the Incra table are always great and satisfying. Also, box joints are easy to do accurately.
I thought about the Festool table when I was upgrading my old table, but decided against it after using it in 3 different classes I took at Festool in Indianapolis. If you are going to use it in a mobile setting on job-sites, I think the table excels in that setting. However, given my use is strictly in my own shop, the Incra table made more sense and, I felt, was easier and more accurate for setup of cuts and joints. Dust collection is probably better with the Festool table but not that much better.
I should add I don't build wood furniture, cabinets, or do remodeling/building for a living so my opinions are from the point of view of getting high quality results for myself and family. I still feel the Incra table has a much higher degree of accuracy for most jobs.
I would also say that I think, for a router table, you want a dedicated router mounted in the table and I feel it would be a shame to mount the OF1400 in a table and not use its versatility and accuracy as a handheld router.
