Which is which?

One of the things I have on my list is to get some braces. I have been wanting to get one but right now I don't have the money to do it. Hopefully in the next year or so. But I can't decide which one will work for me. I kinda like the one where people can't really tell that you have braces but then again I also like the one where you can see it.

I found this Orange NJ invisalign and they really have a lot of information about the invisalign. Come to think of it, maybe I'll just have the invisalign so I won't have an issue with cleaning all the food that will get trap with the braces.

To those who had braces before, could you give me some insights?
