As already mentioned, anti-seize is a dirty mess from hell to clean up from bike, skin and clothing. When you remove your BB to service or replace you need to do a fairly thorough job of cleaning off the threads and is a PITA with anti-seize. Grease of almost any kind that has some moisture resistance lasts a long time and is easier to clean up. I just buy a tub of marine grease which can be used on almost the entire bike; bearings, corrosion protection on seatposts/clamps, metal steerer tubes, metal handlebar stem and bars, fastener threads, etc. Only freehub/freewheel inner bearings need something less viscous in most cases.
