I own the Bosch 1617, PR20 "Colt" palm router, Dewalt 618, and PC 7518.
For my uses;
The palm router is my choice for anything already installed.
The 1617 is a better handheld router than the Dewalt. Both fixed & plunge bases just have a better feeling on them, depth setting for the plunge is better, less vibration, you name it.
The 7518 (and others in its size/amp range, but the PC 7518 is the standard) is the table router. I plan to buy the big Kreg table top, Jessem lift, wixey digital readout, and build myself a cabinet. However the Dewalt is not too shabby in its current home in my (simpler than above) table.
If all I had was the Dewalt I wouldn't be doing bad by any means. I get the feeling the similar kits in Dewalt & Bosch that I have, the Bosch is more built for woodworkers and the Dewalt is built more for the construction world, sacrificing fine 'anything' for durability.
