Well, they're both I'd say equally popular, but you may not care about popularity (like myself), so that being said, I'd pick Isabella over Mikayla. I just think it's much more classy and Mikayla is just too trendy for me. Hope
Mikayla is a pretty name, but I prefer what I think is the original spelling of Michaela. Isabella is also very pretty. Its a tough choice but I think I'd go with Isabella.

My sister named her dd Mikayla, but personally I prefer Isabella.
