How to Choose between Transparency Methods?

Tags: #transparency #color_keying

I'm trying to understand the various chroma based transparency effect filters available and how one would choose between them. I believe I get why one would choose between blue and green. My impression is that one would choose "Chromo Key" if the background were some other color. Please correct me if there is more to this than that. "Non Red" seems self explanatory but can't guess what this is used for, i.e. why "red"?. Can anyone tell me? Then there is "video merge", is there any reason to choose this or not over the preceding chroma keys on a Windows pc?
