Am I a good candidate for Invisalign, or should I take traditional braces? I'm 20 years old.

I have worn braces from 12 till 14. But my tooth have moved and now im at a point where i don't like it anymore. The things that I don't like: - from the side I have lots of space between teeth - my gumline is is not even. I don't mean it vertically, but my gumline is more INwards (see picture from below) - i feel like my canines are too big and pointy and show space between my teeth. - overall, i dont like Should i chose for invisalign or normal braces, or something else? thanks in advance
