I prn them the same, but sometimes I prn Daniela as dan-ee-yell-ah before I correct myself xDI like both Daniela and Daniella, but I think I prefer Daniela. Daniela is also my best friends little sister's name
I would pronounce Daniela / Daniella the same - dan ee elle ah, but I say dan yell ah sometimes too, I like both pronunciations. I prefer the Daniela spelling btw.
