Loose ball bearings and cartridge bearings are not interchangeable. If you mean caged bearings then there can be a performance/longevity disadvantage compared to loose ball bearings. Caged balls are very slightly easier to deal with in BB's.
(I now see the caged balls in the picture. Cartridge bearings are a different animal altogether.)
