I used closed captions a lot since I was young. But closed captions should be on the top of the screen, so it would be much easier for me to find out who they are!
In the UK this is classed as subtitles.look like closed captioning. Some closed captioning do show sounds. At least in some shows.
I dislike subtitles because lack sound effects and so on like Souggy said. I remember watching a movie which is supposedly scary, something to do with strange phone calls. (Sorry cannot remember the name of the movie.) It ruins the suspense when it didn't say the phone is ringing or not. Had to rely on person's reaction to know that it is ringing.
I like closed-captioning because they use captioning with black background. Though I agreed that sometimes the captioning didn't work too well, such as getting behind or appeared to be in gurgle wording. Not all technology are perfect.

CC is so necessary, as it tells everything. Subtitles unless special SDH suck as they don't tell you needed information for enjoying the plot.
