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...

N.B. I've always found those notched headset lockrings to be superfluous. You already have the locknut to hold the adjustment, so why the ring as well? Seems like a "belt *AND* suspenders" approach. You can leave it off and replace it with a simple spacer.

Either the Hozan lock ring tool, one end of which has a smaller radius designed for those rings, or an adjustable hook spanner.
