I'm a brackets guy myself: I think they look the coolest and the most interesting and the different coloured elastics you can get on the brackets are cool to.

"Straight-wire" (if that's the correct term for them) isn't really my style, but when I had real braces to fix my buck teeth I had removable straight-wire ones with a red retainer, I used to chew on them and break them quite a lot  but eventually they did what they were intended to do.

I don't like Invisible they're just boring in my opinion: I'm all about the metal baby 

I like all types of braces except invisalign  my special faverouts are headgear and facemasks and Herbst appliance y one of those is so sexy

Brackets are eventually removed 
My vote is for a Hawley retainer, as it might just be worn forever.

I like metal fixed braces the Most, because they look like cages und you cant take them off. I dont like Invisalign. Removable braces and clear fixed braces arent really my style, but they are better than in braces

To be honest, I also don't understand why brackets should be almost invisible. Whether you recognise braces at first or second glance is negligible if you've had treatment for several years.
At some point, everyone will know anyway. If you need treatment, you should own up to it.
Acceptance was much higher 20 years ago. That surprises me.
