They’re not actually pronounced the same.
Amelia is pronounced A-mee-lya and
Emilia is pronounced E-mee-lya, they’re very similar though.
Maybe I’m biased because it’s the most similar to my own name but I’ve always preferred
Emilia. I may also because friends and family call me
Emilia sometimes. I think it looks and sounds nicer and is less common (at least in Scotland)
Amelia is beautiful as well though.
