AFAIK ctags and etags share the same format. There's a lot of different 
apps that generate TAGS file, e.g. etags, ctags, anjuta-tags; then 
there were some old unsupported ctags, but nowadays by ctags usually 
implied "universal ctags" which is the maintained version of older 
ctags.

I can't answer for the rest of them. But one thing I can tell: tags 
stuff is very popular because it allows to share some infrastructure 
with Vim. Ofc formats are a bit different, but not very much, and 
usually tagging apps can produce both Emacs and Vim formats.

To add even more confusion: nowadays there's an open LSP standard, and 
I think it's the future. It supports a lot of different editors, lots 
of languages, and is more flexible than tags (in LSP, basically, you 
have a separate server running that provides features to editors).
