Stick to cartridges for road use, there has never been a properly sealed cup and cone BB so you end up wrecking them or having to pull them apart every time it rains, which causes premature wear on your crank tapers.
If you're racing on the track, you can pull the rubber seals out of some cartridge BBs, as seal drag accounts for a significant proportion of total losses in the bearings. Some also use standard sized bearing cartridges, opening up the possibility of ceramic replacements. Notwithstanding that, you're unlikely to do better than a very high quality unsealed cup and cone unit (Sugino 75 Super Lap, Hatta R9400) with not too much grease for a super free running feel.
