I would have to say
Baila and
Zoe, only because that is the only set with sufficiently different pronounciation between each name. I don't really care for
Baila, but
Zoe is nice enough. The repeating -ay and -elle sounds in the other set are too much for me, although I like
Maya,
Adelle, and
Ayla (spelled as
Isla) as individual names.
I think the name
Clarissa is a little too frilly, I like
Clara much more.
