Uv sterilizer vs Electric/Steam sterilizer

Hi mommies, hope to get your opinion or experience on this matter. I'm not sure whether to get a uv sterilizer or electric/steam sterilizer for baby's bottle, pacifier and baby's teether. Which one is better in terms of suitability, functions and maintain longer lasting of the the sterilised items? Also, can I sterilize the breast pump and its part? Thanks in advance.
