Bb,
Of the 2, I think Why 1 sounds more like it's all in the same room. i.e. the mix is better. You sound like you are singing with the band.

In example #2 the vocals sound more distant and as though you are not singing in front of the band.

As for your other point about too much or too little sounding on the vocal reverb....the thing to do then, using the onboard reverb for the keyboard, bring it up or down depending on which mic setting you are using. The reverb is going to imitate the space that the mic is creating that you get by switching to omni or uni directional.

In Why 1 it sounds closer to balanced, as far as presence.

Consider putting this tune in on the music project idea I mentioned will you, it's a great tune.

jam on,
