I listen to a bit of music with microtonal stuff. I like it when it is done as a lead line, kind of like hitting blue notes in jazz, or using the extra notes in a bebop scale.

But I don't agree with the chord voicing in the second video. He used too many dissonant chords in a row. It would have been way better if he used standard chords and used the microtones in a lead setup, or had spaced them with nicer sounding chords. It just sounded like he was jamming a whammy or something because of how he chose to play.

The first video they sounded nice, but after a while it was just stacking up a wall of sound rather than creating interesting sounds, because its from the harmonic series, so I don't think it is too desirable in that case. When you venture out of a standard triad, you're looking for interesting sounds that grab you in a particular way. I think those chords as basically open harmonic series do the opposite.

IMHO.

I wouldn't play it. But I like it. I think his licks were pretty nice.
