Not tried the new fuel milwaukees yet but i have owned almost every make. without condsidering the fuels i would put the bosch 36 volt drills at the top of the list based on price and performance. yes even the little one. If you want the best on the market then go for the hilti monster at about 1200 squids. The standard milwaukee 18v sds is very good, prob the best 18v sds ive owned.
i was going to buy the new m18 fuel big daddy sds drill but my van got broken into and i had to spend the money on new hand tools, but if i have one from from santa ill do a review of it.
i own:
bosch 36v sds
bosch 36v compact sds
milwaukee m18 18v sds
milwaukee v28 sds
i have owned/ had stolen:
dewalt 18v sds (li-on)
