Far less so than his predecessor, the saintly Bercow... As far as I'm aware Hoyle has made but one substantial unconventional decision (but that was an egregious howler, selecting Labour's amendment to an SNP opposition-day motion).
The Speaker has limited power when the government has a good majority (by definition the usual case). Less blame attaches to Hoyle than to our failure to separate powers properly in Parliament, where the overtly political LOTH controls Commons business.
