I disagree.
Bosch multi-tool blades are top shelf, wouldn't buy anything else at any price. Their 1/4" bits are good as well, they sell different bit hardnesses...try them all to see what you like, the hardest one seems like it's almost too hard.
Their regular drill bits are so-so, but their masonry bits are pretty good.
Their flap discs are also really good.
A lot of their stuff is made in Germany and of top quality. They're a far cry from all the **** made in China that Milwaukee and DeWalt import.
Fein blades are superior. Only thing bosch I can endorse are jigsaw blades but they're all made in someone else's factory in switzerland.
Apex and vega bits destroy bosch bits. Shockwave, dewalt, makita gold, all junk comparatively speaking.
Makita and Milwaukee (japan and germany) spline and sds bits (and core bits) are actually quite good so this is an exception to my rule.
Grinding wheels, flap discs, diamond blades, diamond cups, I only touch Pearl.
Saw blades, again the power tool brands all junk along with diablo.
