UV is convenient as it can sterilise and dry at the same time. But for sterilisation, steam is just as good. Certain materials are not suitable for UV sterilisation so it depends on which bottle you are using
I bought the steamer after checking with few baby bottle company that their bottle has not tested to sterilise in uv. Just to be on the safe side although uv steriliser is much more convenient.
UV steriliser
Depends on your budget?
