Not to disparage anyone from adding another plug in to their DAW..... but essentially, if you know what you're doing with a basic EQ, Compressor, and reverb, you have the 3 tools you'll need to get good clean vocals already. The delay and chorus are normally not needed for vocals and if you want those, there are generally plugs in the DAW for that as well.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
