Unique structural elements. Nearly every instrument played masterfully. Apart from the vocals, gorgeously harmonic. Yet, even in the harmonic moments, no fear in experimenting in polyphonic, and light avant-garde elements. Plus, distinctly rock in tone(even if the jazz elements are very strong).

Just because it isn't 'serious' I don't think the craftsmanship in terms of musicianship really need to be discredited.

Where as Jethro Tull is significantly more simple rhythmically. Significantly less subtle thematically. More needlessly repetitive. Too focused on that catchy hook which makes rock accessible. Great band, worse example of 'progressing' from rock norms.
