They all make good tools and they all make not so good.
I prefer Makita

for the most part, such as the 10" SCMS, 7 1/4" circular saw, 18 volt drill, R/O sander, palm sander, Belt sander, 12 in thickness planer, air compressor, etc.
I do own some Bosch tools too, 2 1/4 HP Routers, Recip saw, planer, corded drills, Router table, Router bits, etc.
Milwaukee has good stuff too! Though they are not German or Japanese, however they are manufactuered worldwide so they may be both!
Which brand is my choice? Makita, Bosch and any other High Quality tool, I hate cheap junk.
