Definitely less. Tull at least have hard rock/heavy rock influences, especially in their 70ies era. Hard rock in strange meters before Rush did it.
Their live act was pretty hard rockish too, introspective they were not.
Anderson was always cognizant of the fact that Tull were also serving the needs of a hard rock audience as well, not that he sometimes didn't deplore that fact, especially on lengthy US tours where audiences were not always receptive of the finer aspects of Tull's music.
I appreciate Tull's/Anderson's craft and idiosyncratic style, but I tend to tire quickly of his mannered vocals (and the voice mannerisms have become even more blatant over the decades). For some reason, Warchild is my favorite album. Perhaps because it is a bit "glammy".
