I would say regular one. I just bought the leo in the dark pink one, but when it arrived..I didnt like it as much as I thought I would, so I returned it. I like the Blanc Corail one, but it being so light I was afraid it would get dirty quickly.
I have both... But I still haven't used the Leo one, I bought it when it first came out. I really think you should get the Leo now before it's all gone, you can always get the regular Sarah. But Leo won't be around too long.
