Ada pretty much for the reason's you've listed. I also think it's sturdier than
Mira.
Mira is also such a common Spanish word that I can't get past it sometimes. It means "look", but it's also sort of just used to start sentences, like "hey listen up". (Anyone who knows Spanish better than I do can elaborate!)
