I vote for the bon bon especially if your avatar is actually you, I can see you rocking the crap out of the LV.
I think that the Hermes looks a bit boring, sorry I don't mean to offend anyone.
I am 20 and I did find the bon bon a bit tween-like for my taste but I was at the store yesterday and I saw it in real life. It is so fun. You can wear it cross body, as a shoulder bag, or you can hold it folded over like a clutch. On top of that, it is a limited edition and if you ever do sell it, which I hope you won't, you can probably get a good amount of money to go towards your Hermes.
One more thing, I know that this wasn't part of your consideration but I might look into a LV epi noe or petite noe in toledo blue. The shape and size is very similar to the Hermes but its way more fun in my opinion.
