My generation of Americans would probably always use one of these: Thank you; Thanks; Thanks, I appreciate it. Your other choices are all foreign to me.

I sometimes use "cheers" in very informal situations (almost exclusively with men), but otherwise I use only "thank you" and "thanks". I never use "ta" (it's not too common in southern England) and I would never use "wicked". That's just awful.

It's a matter of preference. I use "cheers" often, as well as "ta". With my Indonesian friends I use "tengkyu". "Wicked" is too slangy for me. The problem with slang is that it has a short shelf-life.

Sometimes I'll say "ta" , but mostly saying "thanks".

thank u , i dont like cheers i dont know loool
