Depends on the bike or the build. I usually go with adjustable bearing BBs on all or mostly all original equipped bikes and overhauls. When building up from a bare frame using a mishmash of components then I usually go with sealed bearing cartridges.
Bad Lag I have Phil BBs in about half dozen bikes including one of them that I bought back in 1975 that's been in about 5 different frames.
The last 10 years or so I've been using Shimano UN-55 cartridges and Campy Veloce/Centaur cartridges on a lot of builds.
The Shimano cartridges are selling new for $15-25. I bought a bunch of the Campy BB cartridges for $15 a number of years back.
Last fall I switched the cranks of my 1971 Raleigh Competition beater for gravel grinding. When I bought the bike it had cast SR cranks. I mounted Stronglight 93 cranks to use smaller chainrings and used one of the Campy cartridges. It worked out fine.
The 71 Raleigh had a 66mm wide BB shell rather than the standard 68mm. I had to put two 1mm spacers under the fixed cup to get things to fit properly.
All set for gravel grinding...
