Bastl Microgranny is also an option. It’s pretty basic in the way that it’s only one grain at a time, sort of like when you do granular on a DT or OT, but if that’s the sound your looking for i would say it’s a pretty cool little device.
Zoia does granular too, if you dont mind the very minimal interface.
Still hoping for a dedicated Elektron granular someday, even did a mock-up some time ago :
