Not breaking apart, and not being bad are not the same things. The dual row bearing still suffer from rubber seal failure which displaces the sealed grease. With twice as many balls there is twice as much ferous metal debris that can/will conaminate other bearing surfaces (namely cam and crank surfaces).

The improved durability against breakage/toal failure is a compromise to more metal contamination circulating through the lubrication system.

If you have an engine with a servicable bearing its worth changing as early as possible. IMO
