I voted for the sweet Alhambra. I am biased, I love the clover and the meaning behind this symbol. Also, as was stated it's a safe classic choice. I think it's nice to have a matching set, so when you feel like it you have this option. In my opinion, an Alhambra matching set would work much better for any dressier/ more formal occasions, as opposed to sweet butterfly. Additionally, I find the Alhambra design easier to pair with other jewelry. To sum up, I think sweet Alhambra is much more versatile and will have higher probability to stand the test of time (in a sense of changes of taste, age etc.). All that aside, you should definitely get what makes you happy!
